Does it really need to run non-chroot? You could include a
/mnt/sysimage -> / symlink inside chroot if you have hard-coded paths in
the perl script.

Otherwise, you need to let perl find the library it needs. libperl.so
lives in rpath, so this might work (untested):

%post
cd /usr/lib
ln -s /mnt/sysimage/usr/lib/perl5
/mnt/sysimage/usr/bin/perl your-script.pl


I found the rpath like this:

$ readelf -a perl |grep rpath
 0x0000000f (RPATH) Library rpath: [/usr/lib/perl5/5.8.0/i386-linux-thread-multi/CORE]


Hope this helps,
