With the src/x11 framework, is there a way of doing an equivalent
of hosts.def, eg:

#define UseFreetype2            YES
#define BuildFreetype2Library   NO
#define HasFreetype2            YES
#define Freetype2Dir            /usr/local

#define HasPerl                 YES

? (with the added bonus that it might get the -Wl,-R's right ;) )

Cheers,

Patrick
