I build my own Perl, because it's always a little doubtful whether
libraries (and XS modules) built with a different compiler than Perl
itself is built with will work, even between GCC releases, much less a
wholly different compiler.

Building Perl with GCC is pretty straight-forward, but there are
gotchas--the common GCC message '-b must be at the beginning of the
command' is due to GCC receiving CFLAGS (or LDFLAGS?) intended for xlC
or a direct call to ld.  I noticed with Perl 5.8.7 that there were
problems with the documented way of using GCC, because the Configure
script would use CC=3Dgcc but *FLAGS intended for xlC.  Here's the
incantation I found that worked:

    bash ${PERLSRC}/Configure -des  \
        -Dcc=3Dgcc -Dusethreads       \
        -Dprefix=3D/usr/local/perl5   \
        -Dmksymlinks
