first, you want to use

<code></code>

tags around the painfully long make output so it gets formatted all pretty.

then you might want to move your .cpan cache directory out of the / filesystem.

then i can only wish you good luck, Math::Pari gave me the most problems of any module i've every had the displeasure to have to use. it took days of tweaking/testing to get it to work. copy the tarball from your .cpan cache somewhere, untar it, and read the README and INSTALL (and the ones from libpari) several times. i ended up having to start the make, let it fail, move some files around in the libpari tree, restart the make and let it finish before it would compile and pass it's tests.
