Multiple versions of PetSc

[Amit.Itagi at seagate.com]

Hi,

I have a naive question. I have a program that uses a C++, complex version
of PetSc. I need to run a second program that uses a C, real version of
PetSc. For the first program, I have defined the PETSC_ARCH and PETSC_DIR
variables in my .tcshrc . In order to get the second program working, do I
need to install a second version of PetSc ? How do I separate the
environment variables ?

Thanks

Rgds,
Amit
