Internal error (weird)

[John-John Tedro]

Hey, get this when i try to run automake:

Use of uninitialized value in exists at /usr/bin/automake-1.10 line 4823, <GEN0> line 1.
Use of uninitialized value in concatenation (.) or string at /usr/bin/automake-

Im running this on a Gentoo x86. It occurs even if 
configure.ac is empty.

Also autoconf _always_ gives:

as_func_failure succeeded.
as_func_failure succeeded.

Not typo, it says it twice, no matter what you do.
And it's _not_ shell dependant, tested it with bash and zsh.

Suggestions?
