Failed installation of gcc48 +gfortran breaks earlier gfortran builds

[rouson@…]

Attempting to install gcc48 +gfortran has somehow broken my earlier builds (and thereby brought all of my work to a halt). The trailing lines output from the build follow:

---> Building gcc48 Error: org.macports.build for port gcc48 returned: command execution failed To report a bug, follow the instructions in the guide:

​http://guide.macports.org/#project.tickets

Error: Processing of port gcc48 failed

After this, running gfortran on a simple one-line program produces the following ICE

$cat end.f90 end $ gfortran-mp-4.7 end.f90 dyld: Library not loaded: /opt/local/lib/libppl.9.dylib
