It looks like /run/user/<UID>/ccache-tmp is indeed a path hardcoded into the ccache program.
The documentation says:
"The default is /run/user/<UID>/ccache-tmp if /run/user/<UID> exists, otherwise <cache_dir>/tmp."
If you are certain that /run/user/<UID> does not exist, then perhaps the detection of its existence is faulty on Mac OS X 10.7.5.
The changelog for 4.6 says:
"Ccache now verifies that /run/user/<UID>/ccache-tmp is writable before using it for temporary files."
Perhaps that detection is faulty on Mac OS X 10.7.5 or something else was inadvertently changed/broken during the implementation of this fix.
To install an older version of a port, see https://trac.macports.org/wiki/howto/InstallingOlderPort
