There's no 'F' in compatibility (distcc troubles)

[john.robinson]

I'd like to get distcc up and running. My Gentoo box is a poor slow i586 (actually 500MHz AMD K6-2). My other box, running Fedora, is a rather faster i686 (1GHz AMD Athlon). I thought, yes, distcc, splendid idea.

(1) Gentoo's distcc 2.11 doesn't want to talk to the 2.12 I built myself on the Fedora box. Or something. Setting all up properly (per http://www.gentoo.org/doc/en/distcc.xml I think), `emerge which` hangs at "Detecting executable suffix"; ctrl-c to get out leaves lockfiles in .distcc/lock which I have to remove by hand.

(2) How am I supposed to run the right gcc? On Gentoo, I have gcc 3.2 and if I want to change gcc version I'm supposed to use gcc-config then run `gcc`. On Fedora, I have gcc 3.3 (default) and 3.2 and I'm supposed to run `gcc32`. I ought to be able to say `gcc -V 3.2` on both, according to the gcc man page, but neither distro makes this work. Why oh why oh why???

Aaargh my head hurts, it's time for bed.
