----------------------------------------------+-----------------------------
 Trying to install physfs-2.02 on a Lion installation results in several
 "deprecated" warnings, which, due to the "-Werror" flag which is used by
 the default physfs-build, seem to abort the build.

 This appears to be rather a physfs- than a MacPorts-problem (not sure if
 it can / should be circumvented in the MacPorts build), but for the time
 being it seems that removing the -Werror flag from "CMakeLists.txt" in the
 physfs sources makes the build complete without errors.
