Solution see below - but I'd be interested in your exact setup.  
Please send me the version information of all compilers involved.

This comes from a work-around for the incompatible ABI of gfortran.  
For some strange reason (I'd like to know why) your gfortran seems to  
append two underscores.

The 'hot-fix' for your particular setup is to edit src/modules/lapack/ 
vecLibg95c.c and replace everything between #ifdef and #endif at the  
beginning of the file by one simple
# define F77_SYMBOL(x)   x ## __

In the meantime I'll see if I can get a better fix committed.

Thanks,
Simon
