hdfeos fails to build if configureccache yes is in macports.conf:

Warning: the following items did not execute (for hdfeos): org.macports.activate org.macports.configure org.macports.build org.macports.destroot org.macports.install
Log for hdfeos is at: /opt/local/var/macports/logs/_Users_rschmidt_macports_dports_science_hdfeos/main.log

The attached patch works around the problem by disabling ccache for hdfeos. A better solution might be to fix hdfeos so it works with ccache (if indeed ccache works with h4cc).
