First, do you really want 5.6.2? It's almost 5 years old. The current
release is 5.10.0.

This is odd. miniperl should never be loading File/Glob. Your build log clearly
shows opmini.c was correctly built with the -DPERL_EXTERNAL_GLOB flag.

Is there a pre-existing libperl already installed? If so, then perhaps
we're incorrectly picking up the pre-existing libperl.
If there is no pre-existing libperl, then I speculate the problem may be a
subtle one related to how Mac OS handles name resolution. Specifically,
it looks like it's picking up the version of Perl_ck_glob() from op.o
(which is inside libperl.dylib) instead of the version in opmini.o,
which is linked directly to miniperl. There may be some appropriate
linker flag we can use to suppress that behavior. Or, perhaps, we need
to build miniperl by directly linking against all the objects instead
of linking against libperl.dylib.
