Error loading some dynamic libraries

Hi,

I have successfully compiled and installed root, geant3, fluka and aliroot in my laptop. All the tests examples in root have run OK.
But testing some examples with aliroot I have now the following error when loading some dynamic libraries. They are: libgeant321.so and libpythia6.so

You should address this question to the Alice mailing lists, not at this forum.
