[petsc-users] Strange error(?) message

[Mohammad Mirzadeh]

Thanks Sean. I'm using Petsc 3.2-p6 along with ParMetis 4.0.2. Since this
was not supported with 3.2-p6, and previous versions had bugs, I built
parmetis myself and used --with-parmetis-include and --with-parmetis-lib
flags to build petsc.

Should I switch to petsc-dev?
