[SOLVED]: Error install (gentoo) in setup_mta(): makeuserdb returns error 255!

[pgentoo]

Here's the debug output from the setup process, starting with entering the setup_mta() method:

ispcp ~ # ls -la /usr/sbin/makeuserdb
-rwxr-xr-x 1 root root 3272 Mar 22 16:15 /usr/sbin/makeuserdb



Running this alone doesn't show any errors:

ispcp ~ # /usr/sbin/makeuserdb

ispcp ~ #




Anyone have any ideas?
