You will generally get a faster response by posting to the mailing list (devel@lists.nfs-ganesha.org) than by mailing contributors directly.

FSALs are loaded by the fsal_manager in fsal_load.c.  The library that is loaded is <libdir>/ganesha/lib<fsal>.so  where <fsal> is the Name given in the config for that FSAL, transformed to lower case.  You will need to make sure there are 3 things done correctly:
1. The name of your fsal library must match the name given in the config
2. Your fsal must be installed in the correct location
3. Your fsal must have MODULE_INIT and MODULE_FINI functions built into it.

Without seeing the source, it's a bit hard to debug.
