I'm glad to hear that. It could have turned out that the 10.3 libraries I link to
were incompatible with 10.4 libraries. That was a problem I had between
10.2 and 10.3. I don't have tiger yet.

That is interesting. It used to be the case that os x did not have a dlopen, dlclose
unix style for dynamically loading shared objects. Therefore the file nrn/src/nrnoc/osxdlfcn.c
was used to interface between standard unix style dlopen and the mac os x style
NSCreateObjectFileImageFromFile

I guess my version is obsolete but I would have to install tiger in order to verify
that the mac supplied dlopen will work for us. I believe the warnings are benign
and you are using my version of the dlopen.
