[petsc-users] out of date warning when petscmpiexec.

[Syvshc]

I run this command in the root dir of my petsc, and didn't get any response.

What do you get - if you invoke the following command in petsc source dir?

make -q -f gmakefile libs

[this is the test petscmpiexec is using to check if "libraries are out of date"]
