I've not built packages, but I've built it in /usr/local.  If anyone has 
any packages avalible could they please tell me about them so I can put 
them in the PGCC FAQ?  If you don't have any space to upload them I can 
provide some.

Last time I asked the Debian gcc maintainers, the main reason for its
absence appeared to be a lack of people willing and able to do the job 
rather than anything else.

You can probably convince it to build without too much hacking at the
dependancies, or you could just upgrade perl (which works now).  Or just
carry on using your existing package.

It's not supported that I'm aware of.  

Note that the two versions are (bugs in the user package aside) source 
compatible, so if all you want to do is build a new version of the package 
there shouldn't be any problems.  It's only a problem if you want to run
glibc2.1 binaries on a glibc2.0 system.

Benchmarking.  Even if the compiler thinks it is generating code
optimised for your processor, there's no guarantee that it will
actually run any faster.
