No, PAR::Packer should have done that for you. Note that your strace
for RHEL also shows incorrect behaviour (though the search for libssl
eventually succeeds): the packed (and extracted) libraries should come
FIRST in the search, BEFORE the system libraries.
Can you check the setting of LD_LIBRARY_PATH for a packed executable
(assuming that FreeBSD uses LD_LIBRARY_PATH for the
search path for shared libraries):
$ pp -o show-path.exe -e 'print "LD_LIBRARY_PATH=$ENV{LD_LIBRARY_PATH}\n";'
$ ./show-path.exe
LD_LIBRARY_PATH=/tmp/par-user/cache-4631c3f3001de1fe9763584faea848e820073e66
Also check the custom Perl interpreter: in the above example
the cache directory
/tmp/par-user/cache-4631c3f3001de1fe9763584faea848e820073e66
should contain a file named show-path.exe (i.e. the same name as your
packed executable); please run readelf on it:
$ readelf -d
/tmp/par-ccm_root/cache-1ad335c61a0de3ec3f1947d87dbd4ab04eb02f06/show-path.exe
