Ok - so for whatever reason your petsc build were indeed out of date - and "make -f gmakefile libs" updated the library.
Wrt out-of-date executable message - I think its due to the old formatted makefile.
You can do the following:
- edit p4pdes/c/ch1/makefile
- remove the line: ' ${RM} e.o'
- run 'make e'
Now retry:
petscmpiexec -n 1 ./e
