#60322: libtorrent-rasterbar: build fails when ccache is enabled
------------------------+----------------------------------
 Reporter:  ryandesign  |      Owner:  dbevans
     Type:  defect      |     Status:  assigned
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.6.2
 Keywords:              |       Port:  libtorrent-rasterbar
------------------------+----------------------------------
 When the use of ccache is enabled in MacPorts (`configureccache yes` is
 set in macports.conf, the ccache port is installed, etc.), MacPorts will
 set `CC` to a value containing a space, such as `ccache /usr/bin/clang`.

 A [changeset:d64154202f73f594aa482a986e22dcfcbc54c6ac/macports-ports
 patch] was recently added to fix [ticket:60261 another problem]:

 }}}

 These two facts result in a build error when ccache is enabled:

 {{{

 }}}

 If I fix the patch to quote `CC` like this:

 {{{

 then the build fails with a different strange error:

 }}}

 In other words, compiling succeeds, but linking fails because it's
 inexplicably trying to invoke `/usr/bin/clang++ /usr/bin/clang`. I haven't
 yet been able to figure out why this is so.
