Yeah, that's because we have a copy of minizip which happens to uses the OF 
macro.

You can probably fix the issue with the following patch (untested) :

$ svn diff port/cpl_minizip_ioapi.h 
Index: port/cpl_minizip_ioapi.h
===================================================================
--- port/cpl_minizip_ioapi.h	(révision 24142)
+++ port/cpl_minizip_ioapi.h	(copie de travail)

 #include "cpl_vsi.h"
 #define uLong64 vsi_l_offset
 
+/* Gentoo removed OF from their copy of zconf.h 
(https://bugs.gentoo.org/show_bug.cgi?id=383179) */
+/* but our copy of minizip needs it. */
+#ifndef OF

+#endif
+
 #define ZLIB_FILEFUNC_SEEK_CUR (1)
 #define ZLIB_FILEFUNC_SEEK_END (2)
 #define ZLIB_FILEFUNC_SEEK_SET (0)

I'm a bit hesitant to apply that for now. Hopefully Gentoo will revert their 
change under user pressure. Please complain loudly in the ticket ;-)
