But you don't know the reason and just fixed the symptom. Fair enough
from operation point of view - but not enough for reasonable fix.

I'm pretty sure it has nothing to do with perl but with some other
things going on there ...

Well - that's not perl fu (foo?) - it's about setting CFLAGS and LDFLAGS. I
proved over my pkgsrc and perlbrew installations - I see that nowhere. The
weird path's and --whole-archive 
(http://stackoverflow.com/questions/805555/ld-linker-question-the-whole-archive-option)
makes me believe that the system is grown and likely not sane. Tiny quirks
might lurk in the deep and you recognize(d) symptoms of relics.
