Comment:

 "unable to infer tagged configuration" is a message printed by libtool
 when the compiler used to compile libtool differs from the compiler used
 to compile the port being compiled now, using libtool. In this case, the
 difference is that the compiler used to compile libtool was "ccache
 /usr/bin/g++-4.2" (because the user has "configureccache yes" in their
 macports.conf, or at least did at the time they built the libtool port),
 and the compiler now being used to build exiv2 is "/usr/bin/g++-4.2"
 (because the exiv2 portfile has the line "configure.ccache no" thereby
 disabling ccache support). This was caused by a combination of r45058
 (which made the exiv2 port use the libtool port, because exiv2 0.18's
 configure script was generated by autoconf 2.61 and the libtool it
 generated was too old to build universal binaries properly) and r73142
 (which disabled the use of ccache with exiv2).

 I fixed the problem in r77658 by undoing r45058, since exiv2 0.21's
 configure script was generated with autoconf 2.67, which is new enough to
 support universal builds on its own. Additionally, in r77659 I undid
 r73142 because it builds fine for me with ccache.
