------------------------------------+---------------------------------------
 I have observed that gtk2 @2.14.5_0 does not utilize the ccache build
 support even if MacPorts has been configured to use ccache.
 The gtk2 port appears to explicitly deactivate ccache support in [36623]
 with a
 {{{
 configure.ccache            no
 }}}

 However, that revision's log message does not refer to any feature change
 or bug that requires turning off ccache. (It also adds
 {{{
 use_parallel_build  yes
 }}}
 to the gtk2 Portfile, which also does not seem to have anything to do with
 any of the items mentioned in the log message, and it appears to be
 another override of the MacPorts build configuration)

 Is there a particular reason for deactivating ccache for the gtk2 port?
