Question on gcc for pkgsrc with centos/rhel

[Daniel Vergien <daniel.vergien%rrz.uni-hamburg.de@localhost>]

Hi,

I'm trying out pkgsrc on centos. I have gcc ang gcc-c++ installed from 
the systems repositories (version 4.1.2). Bootstraping works fine, but 
when I want to compile packages like lang/perl5 it pulls in 
lang/gcc3-c and other packages pull in lang/gcc34. I wonder why this 
is like that. I tried to set CC, CXX in mk.conf like I was used to 
when I used sunpro on solaris, but it did not change something.
Do I really need to build all these compilers?

Regards

Daniel
