Thanks. So far my first port from fink hasn't turned out that well. The molmol
build that works fine under openmotif4 (2.3.2) on fink doesn't properly display
its windows under the openmotif and glw packages in MacPorts. I am afraid I
am bumping into a bug in one of those packages. After I clean the port up a bit,
I'll submit so that the openmotif and glw maintainers can take a look at this
issue.
