Here configure thinks FBLASLAPACK is already built.

But here - the compiler is not finding the library.

So the library is not likely built.

You can either do:

rm -rf /home/ryan/projects/moose/petsc/linux-c-opt/

i.e delete all build files - and start a fresh build.

Or delete the file configure looks for and assumes this package is built - i.e

rm -f 
/home/ryan/projects/moose/petsc/linux-c-opt/lib/petsc/conf/pkg.conf.fblaslapack

and rerun configure.
