needing to change default compiler?

[Christopher Howard]

Hi. I'm not even going to pretend to be a Perl programmer (I used it years
ago once.) However, I am trying to use CPAN to install a newer version of
the DBI module, because the application I am trying to run needs a newer
version than the one installed on the system (I have no admin privileges).
From inside the CPAN shell, I attempted 'install DBI', but eventual the
build fails with:

It seems that "pgcc" does not recognize these switches, so why is cpan
using pgcc instead of gcc? If this is the problem, how do I change CPAN's
default compiler?

I am working on a SUSE Linux system with Perl 5.10. The CPAN shell version
seems to be 1.9205.

Try it from outside the CPAN shell. The CPAN shell does nothing but wrap
the usual incantation:

perl Makefile.PL
make
make test
make install

I do not expect that this will work better but it makes it more obvious
where you have to tweak things: with parameters to 'perl Makefile.PL'.
You will find the ExtUtils::MakeMaker documentation indispensable. When
your default compiler is not the right one you will most probably need
more than one such parameter. For a start I'd try

perl Makefile.PL CC=yourcc

Good luck,
