It does work.
Just tried ./configure --download-slepc --download-bamg --with-petsc4py '--download-slepc-configure-arguments=--with-slepc4py=1 --have-petsc4py=1' --with-fc=0
No issue whatsoever.
Matt, you should probably force that flag (--have-petsc4py=1) in bamg.py (and you should change '+carg+'./configure to '+carg+self.python.pyexe+' ./configure as in slepc.py)

Thanks,
Pierre
