[distcc] First remote execution works, second fails.

[MAL]

Hi,

I'm using distcc with Gentoo to compile software via portage, on my aged 
laptop, with help from my Athlon XP system.

The Athlon XP is called mal, the laptop is the machine that I run emerge on.

For those who haven't used Gentoo, Portage is basically a compilation 
front end that sorts out dependencies, compiles, and performs virtual 
installs, followed by merging an app into a running system... it's the 
package manager for Gentoo.

Gentoo does some interesting things with the locations of gcc and g++, 
in that it keeps the binaries in (on my pc):
/usr/i586-pc-linux-gnu/gcc-bin/<gcc_version>/

and sets up the PATH environment variable to point to them. This is so 
multiple compilers can be present without interfering with each other.

It's taken me a good few attempts to get it working to begin with, as 
the environment wasn't staying the same while emerge ran, (the various 
gentoo-distcc howtos online no longer work... I guess the changed in 
gentoo's gcc layout).

Anwyay.. it appeared to work, but then I get this (see attachment). 
groff failed on the second remote call to g++, (looks like the first 
worked fine).

This is just a sample package, the same happens with others.

Note: my DISTCC_HOSTS only contains "mal", and not localhost.. do I 
absolutely need localhost?  (the local machine is a 20th as fast as the 
remote machine).

Sorry for the length, any ideas people? :)

Cheers,
MAL
