This can be fixed by adding

  OTHERSHAREDLIBS = ${SLEPC_EXTERNAL_LIB}

to conf/slepc_common_variables but you still have to add -lpetsc
-lpetscksp -lpetscdm ... to prevent undefined references to PETSc
functions. Should we also link the SLEPc shared library against the PETSc
libraries? We can do this by using

  OTHERSHAREDLIBS = ${SLEPC_EXTERNAL_LIB} ${PETSC_KSP_LIB}

How does that sound?

Best regards,

Johannes
