Hello!

On Mac OS X 10.4.11, Tiger (PPC), configure shows, when trying to install with MacPorts:

This presumably is not the fault of the libtool project but of the MacPorts libtool Portfile which sets:


configure.fc            no
configure.f77           no


(which causes the environment variables FC and F77 to be set to "no").


Why it does this is explained here:

Alright! So no bug at all.

If my theory of relativity is proven successful, Germany will claim me as a German, and France will declare that I am a citizen of the world. Should my theory prove untrue, France will say that I am a German, and Germany will declare that I am a Jew.
