Yes, I set it before running distccd. As for starting, I do it
manually, invoking distccd directly (as I don't see any configuration
files included in the distccd package for openSUSE, so that's the
easiest way to set up permissions). That said, I noticed that it also
noted that user "distcc" was not found. Looking at the system monitor,
it seems that it defaults to running as "nobody". But even if I set it
to use my user as a base, the error is the same. And I can definitely
invoke the compiler by entering the same name.

As for the permissions, well:
  $ ls -l /usr/local/bin/
  -r-xr-xr-x 1 root root 665272 2012-09-04 07:06 i686-pc-linux-gnu-gcc
