I use ccache with pkgsrc all the time.  But I use
   CCACHE_DIR=          /home/gdt/.ccache

So I sugggest:

    set CCACHE_DIR to a directory that is permanent (no tmp flavor)

    make sure it's writable by the user doing the build.

And I think this is a clue:

[2013-08-13T18:20:27.911465 9563 ] Unsupported source extension:
[2013-08-13T18:20:27.911487 9563 ] Failed; falling back to running
the real compiler

I believe my CCACHE_DIR setting is appropriate in this case, as /var/tmp/pkgsrc survives reboots but is reserved for pkgsrc. I'll keep $HOME/.ccache for non-pkgsrc builds.

Indeed, I believe there is something to do with the extension as indicated in my original post. I tried a couple of other packages all to the same effect. Does anybody have this working?

What I do notice from the ccache.c source code (and, for that matter the "Using the GNU Compiler Collection") is that the syntax supported for spec-files is '-spec=file' and not '-spec file'.

Can't seem to find in mk/* where to change the generation of this syntax...
Any clues?
