gaim depends on tcl

I think all that is happening is that redhat's build system doesn't have
a minimal environment for building rpms in.  The package gets built
inside an environment with tcl installed, configure picks it up, and the
resulting package is built with tcl dependencies.

Another point in favour of clean build roots.
