You often do need to worry about versions, sadly. This is why different distributions often have their own packages. You may be able to be more specific about what version it uses, i.e. -lgtk-version instead of -lgtk, so that it gives 'file not found' instead of crashing when supplied with an incompatible version. Libraries are usually available under many names from the most generic to the most specific, allowing programs to be as picky or generic as will work:

Code:
lrwxrwxrwx 1 root root      11 Aug 26  2014 libpam.so -> libpam.so.0
lrwxrwxrwx 1 root root      16 Aug 26  2014 libpam.so.0 -> libpam.so.0.83.1
-rwxr-xr-x 1 root root   55760 Aug 26  2014 libpam.so.0.83.1

so linking to generic 'pam' means 'I expect this program to work with any PAM from any era', linking to pam-0 means 'I expect this to work with any version 0.*', and linking to pam-0.83.1 means 'this program will work with only this exact version of pam'

If you could find out what version of GTK you have in your emulation packages that might help solve the mystery. Try ldd ./myprogram to see what libraries it has ended up using.

Lastly, I'd note that you haven't actually ruled out a bug in your program yet. More may have changed than you realized in moving from one machine to another of any bit width. Recompile with debugging info, and check through your program step by step as it runs on the 64-bit machine (i.e. using gdb).

SETARCH(8)						       System Administration							SETARCH(8)

NAME

       setarch - change reported architecture in new program environment and set personality flags

SYNOPSIS

       setarch arch [options] [program [arguments]]
       arch [options] [program [arguments]]

DESCRIPTION

       setarch	This  utility  currently only affects the output of uname -m. For example, on an AMD64 system, running 'setarch i386 program' will
       cause 'program' to see i686 (or other relevant arch) instead of x86_64 as machine type. It also allows to set various personality  options.
       The default program is /bin/sh.

OPTIONS

       -v, --verbose
	      Be verbose.

       -h, --help
	      Display help (it is also displayed when setarch takes no arguments).

       --uname-2.6
	      Causes the program to see a kernel version number beginning with 2.6.

       -3, --3gb
	      Specifies that processes should use a maximum of 3GB of address space on systems where it is supported (ADDR_LIMIT_3GB).

       -B, --32bit
	      Turns on ADDR_LIMIT_32BIT.

       -F, --fdpic-funcptrs
	      Userspace function pointers point to descriptors (turns on FDPIC_FUNCPTRS).

       -I, --short-inode
	      Turns on SHORT_INODE.

       -L, --addr-compat-layout
	      Changes the way virtual memory is allocated (turns on the ADDR_COMPAT_LAYOUT).

       -R, --addr-no-randomize
	      Disables randomization of the virtual address space (turns on ADDR_NO_RANDOMIZE).

       -S, --whole-seconds
	      Turns on WHOLE_SECONDS.

       -T, --sticky-timeouts
	      Turns on STICKY_TIMEOUTS.

       -X --read-implies-exec
	      Turns on READ_IMPLIES_EXEC.

       -Z, mmap-page-zero
	      Turns on MMAP_PAGE_ZERO.

EXAMPLES

       setarch ppc32 rpmbuild --target=ppc --rebuild foo.src.rpm
       setarch ppc32 -v -vL3 rpmbuild --target=ppc --rebuild bar.src.rpm
       setarch ppc32 --32bit rpmbuild --target=ppc --rebuild foo.src.rpm
