System: Darwin max.local 7.6.0 Darwin Kernel Version 7.6.0: Sun Oct 10 12:05:27

>Description:
Darwin 7.6 has libdl (a symlink to libSystem, which is libc) and dlopen()
is available, but building perl58 pulls in dlcompat.

% nm /usr/lib/libdl.dylib | grep dlopen
900f891c T _dlopen

it should not be necessary to pull in dlcompat on Darwin 7.6.
>How-To-Repeat:
build perl58 on Darwin 7.6.
