There the immediate problem is that
libcharsetdetect/nspr-emu/prcpucfg.h recognises kfreebsd-* with
neither defined(__linux__) nor defined(__FreeBSD__). It's possible
both would work, but I think the Linux way is safer as the macros
being tested and set relate to the userland. So, following the
suggestion given in
http://sourceforge.net/p/predef/wiki/OperatingSystems/, I'd suggest
this untested patch:

--- prcpucfg.h.orig
+++ prcpucfg.h
@@ -34,7 +34,7 @@
 #include "prcpucfg_win.h"
 #elif defined(__APPLE__)
 #include "prcpucfg_mac.h"

 #include "prcpucfg_freebsd.h"

I'll see if I can create an "issue" there.
