We need configure.log
You do not need --download-blaslapack Apple always has them
As of OS X 10.9 the BLAS Apple provided was known to have bugs. I only
noticed any issue (If I remember correctly, "make test" failed) when
configuring in single precision. However, this might be a reason to have
petsc download BLAS/Lapack despite the libraries being available in
Apple's framework.
Suggest just running without passing the compiler names also.

Hi all,
I just updated to OS X Yosemite. I have the latest XCode and also reinstalled
command line developer tools.
When I try to install PETSc, I get the following error:
./configure --with-cc=gcc --with-cxx=g++ --with-fc=gfortran
--download-fblaslapack --download-mpich --with-debugging=0

Can someone explain to me what's going on here?
Thanks,
