PERL package and ld-elf.so.1

[Chris Rodgers]

Hi

I have just upgraded PERL to perl-5.1.6.1._14 using the packages from
freebsd.org on a machine running 5.1-release. However, when I now try to run
PERL it says

701 firewall / # perl
ELF interpreter /libexec/ld-elf.so.1 not found
Abort trap

If I create a /libexec and copy ld-elf.so.1 from /usr/libexec in there, perl
seems to work. Can someone explain what's happened here and how I can fix
it?

Many thanks!
