What package would I need to get this file? SUNW_1.22.7. Please help. thank you.

Be as clear as possible when posting questions...what command gave you that output as libc.so.1 is the std C shlib and "libc.so.1 (SUNW_1.22.7) => (version not found)" doesnt make any sense so post the output of these commands...

ls -latr /usr/lib/libc.*
ldd -v /usr/lib/libc.so.1

I think that I have the same problem. That output I receive when I perform ldd on installed application.

ldd -v /usr/lib/libc.so.1

   object=/usr/lib/libc.so.1; filter for /usr/lib/ld.so.1

   object=/usr/lib/libc.so.1; filter for libm.so.2

   find object=libm.so.2; required by /usr/lib/libc.so.1
        libm.so.2 =>     /lib/libm.so.2

   find object=libc.so.1; required by /lib/libm.so.2
   find version=libc.so.1
        libc.so.1 (SUNW_0.7) =>  /usr/lib/libc.so.1
        libc.so.1 (SUNWprivate_1.1) =>   /usr/lib/libc.so.1

ls -latr /usr/lib/libc.*
lrwxrwxrwx   1 root     root          19 Apr  5  2011 /usr/lib/libc.so -> ../../lib/libc.so.1
lrwxrwxrwx   1 root     root          19 Apr  5  2011 /usr/lib/libc.so.1 -> ../../lib/libc.so.1

What operating system and version are you on?

Version of OS:
SunOS 5.10 Generic_139556-08 i86pc i386 i86pc

No there is no workaround for this and you have to install the patch that updates libc.so to the relevant version...
Go through the files that are updated by the patch and determine if libc.so is upgraded to the version that is expected by your application which in this case would be 1.22.7...
