Bugs: Building CIAO from Source
Building sherpa using pre-compiled XSPEC library requires same version of gfortran
Users building sherpa from source with the CIAO pre-compiled binary OTS packages (recommended) may run into a problem that the version of FORTRAN used to build XSpec must be the same as is used to build sherpa.
Specifically this means that sherpa must be built to link against libgfortran.so.3
Users may need to recompile the XSpec models library with the same version of gfortran.
