Thank you Bakunin.

I have doubt in the flags I set while I compile. For Eg. I compiled an extra library required for ffmpeg (libdc1394) at /usr/local/myapps/lib/libdc1394.so. I then set these ENV variables and compile ffmpeg using the below option.

Code:
LIBS=-L/usr/local/myapps/lib/
export LIBS

PKG_CONFIG_PATH=/usr/local/myapps/lib/pkgconfig/
export PKG_CONFIG_PATH

LDFLAGS=-L/usr/local/myapps/lib/
export LDFLAGS

CPPFLAGS=-I/usr/local/myapps/include/
export CPPFLAGS

PATH=/usr/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin::/root/bin:/usr/local/myapps/bin
export PATH

FFmpeg compilation.
Code:
./configure  --enable-libdc1394
make
make install

Contents of /usr/local/myapps/lib/pkgconfig/libdc1394-2.pc
Code:
# cat /usr/local/myapps/lib/pkgconfig/libdc1394-2.pc
prefix=/usr/local/myapps
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: libdc1394
Description: 1394-based DC Control Library
Version: 2.1.3
Libs: -L${libdir} -ldc1394
Cflags: -I${includedir}

Ffmpeg binary compiled fine. But when I checked "/usr/local/myapps/bin/ffmpeg -v" with strace, I could find, it not taking the /usr/local/myapps/lib/libdc1394.so. It takes "/usr/lib/libdc1394.so.22". Please see the corresponding line in strace output.

Code:
open("/usr/lib/libdc1394.so.22", O_RDONLY) = 3

I need the /usr/local/myapps/lib/libdc1394.so.22 being used during ffpmeg install. There is NO option like "--enable-libdc1394=/path/to/libdc1394"

devel::loaded

Devel::Loaded(3pm)					User Contributed Perl Documentation					Devel::Loaded(3pm)

NAME

       Loaded - Post-execution dump of loaded modules

SYNOPSIS

	   perl -MDevel::Loaded -Sc programname 2>/dev/null

DESCRIPTION

       The Devel::Loaded module installs an at-exit handler to generate a dump of all the module files used by a Perl program.	If used in
       conjunction with a perl -c, you find those files loaded in at compile time with "use".  If you are willing to wait until after the program
       runs, you can get them all.

EXAMPLES

       This is compile-time only:

	   $ perl -MDevel::Loaded -S -c perldoc 2>/dev/null
	   /usr/local/devperl/lib/5.00554/Exporter.pm
	   /usr/local/devperl/lib/5.00554/strict.pm
	   /usr/local/devperl/lib/5.00554/vars.pm
	   /usr/local/devperl/lib/5.00554/i686-linux/Config.pm
	   /usr/local/devperl/lib/5.00554/Getopt/Std.pm

       This will also catch run-time loads:

	   #!/usr/bin/perl
	   use Devel::Loaded;
	   ...
