i don't know much about macs, but on linux i've been having the
best experiences with self-compiled vmd and everything using
the "native" packages (with dynamic linking). that renders the
resulting executable rather non-portable between distributions
and releases, so to have a widely compatible distribution of VMD,
the provided binaries cannot link dynamically, but due to its
wrapping of dynamical objects python implicitly re-introduces
this non-portability. IED not only uses python but through python
also Tk, which VMD uses itself, so you have to make sure that
_everything_ is in sync. if you have a fedora linux box, you
may want to try out the rpms that i deposited into the biocore
(not fully up-to-date i have to confess).
i suspect that on different mac os versions there are similar
issues and perhaps there are some additional dynamic linkers
issues that you are running in.
cheers,
axel.
