The reason it fails to generate a pkg-config file for SLEPc might be that
you need to add the location of the SLEPc library to your LD_LIBRARY_PATH
environment variable. Try something like this (all on one line):

export LD_LIBRARY_PATH=$SLEPC_DIR/lib/$PETSC_ARCH:$LD_LIBRARY_PATH

Then run scons again. If that fails, you could try to run the pkgconfig
generator scripts under
scons/simula-scons/simula_scons/pkgconfiggenerators/ manually. Here is a
suggested set of commands you could try out:

export PETSC_DIR=/usr/local/petsc
export PETSC_ARCH=linux-gnu-cxx-opt
export SLEPC_DIR=/usr/local/slepc
export LD_LIBRARY_PATH=$SLEPC_DIR/lib/$PETSC_ARCH:$LD_LIBRARY_PATH
python scons/simula-scons/simula_scons/pkgconfiggenerators/petsc.py
python scons/simula-scons/simula_scons/pkgconfiggenerators/slepc.py

If any of these commands fails, please report back with the error message.
If every command succeeded, two pkg-config files will have been generated
in the current directory: petsc.pc and slepc.pc. Copy these two files to
the scons/pkgconfig/ folder and run scons again.

Hope this helps,
Johannes
