Comment(by jk@…):

 Hi Roy,

 your patches lead me to the follwing result:
 {{{
 :debug:configure Using compiler 'MacPorts Apple gcc 4.2'
 :debug:configure Executing org.macports.configure (virtualbox)
 ...
 :info:configure Checking for gcc:
 :info:configure   ** CXX is empty!
 }}}

 Configure aborts after this...
