Comment(by raphael@…):

 Your log says:

 {{{
 :info:configure   Manually-specified variables were not used by the
 project:
 :info:configure
 :info:configure     USE_PRECOMPILED_HEADERS
 }}}

 So, the if statement in the portfile works, but
 {{{USE_PRECOMPILED_HEADERS}}} is ignored. The new patch in the attachment
 should do the right thing.
