Looks like a perl issue to me.  Note the lack of a space before the  
backslash on the -DHAS_TMPL_RETENTION line.  "preprocessor.pl"  
appears to be mistakenly joining things together, resulting in the  
failure.  Further investigation needs to be carried out there by  
someone more familiar than me with the mozilla build process.

It should be noted, however, that both www/mozilla and www/firefox  
built successfully here (x11/gnome2 was one of the test cases) on 6- 
STABLE /i386 and /amd64.
