Problems compiling bluetooth module

Wed Jan 5 13:17:44 EST 2011

I've forgot to mention that I get this warning when compiling the modules:

WARNING: Symbol version dump
/home/root/rpmbuild/SOURCES/linux-2.6.31/Module.symvers
           is missing; modules will have no dependencies and modversions.
