One of the major "outside" variables is the tool-chain you use - -
For that reason, I suggest you use one of the "Build From Source"
distributions.  At least you know your tool chain is working.  ;)

Personally, I use both 32-bit and 64-bit Gentoo.
Also, I avoid doing any updates that would change the tool chain
while in the midst of trouble shooting something.
Just keep your hands off of the --update button. ;)

Currently (both flavors, 32/64):
gen2-32# gcc-config -l
 [1] i686-pc-linux-gnu-4.1.2 *
 [2] i686-pc-linux-gnu-4.3.2

The 4.1.2 tool chain is "good" across the board for all Gentoo archs.
The 4.3.2 tool chain is not marked as "good" for hp-parisc.
