The rhug/configure has a bug preventing rhug from configuring when
when srcdir=".".  The problem is that dirpart gets set to the empty
string, which causes teh following mkdir "$dirpath/$DEPDIR" to fail.

configure claims to be generated using Autoconf 2.52g.  This bug
appears to also be in the aclocal.m4 in the CVS autoconf, so the
bug isn't rhug per se.  However, aclocal.m4 is auto-generated,
and I don't see where it is generated from. (I don't understand
the autotools that well.)  In any case, I'll report the problem
to the autoconf mailing list.
