>Description:
If you have devel/ccache installed and ${LOCALBASE}/libexec/ccache in your path to benefit from it, dependency check is faked by the symlinks to ccache in the directory and ports that depend on a specific gcc version fail to build.

This is caused by bsd.gcc.mk not specifying the full path of a gcc binary in BUILD_DEPENDS/RUN_DEPENDS .

>How-To-Repeat:
Install devel/ccache and have /usr/local/libexec/ccache in your path, deinstall lang/gcc45 if it is installed, and try building math/blas for example.
It fails with a message saying gfortran45 is not found, while the port tells USE_FORTRAN=yes which should add lang/gcc45 as dependency.

>Fix:
Apply the attached patch.
