GTS (libgts) version mismatch

[Drew Parsons <dparsons@debian.org>]

Hi Stephane and Ruben,

I'm updating the version of gerris in Debian (using the 2012-04-27
tarball).

There is a build failure halfway through due to Debian's libgts-dev
being out of date.  The latest version of GTS (2012-04-26) has GTS_OBJ
added to the GtsTokenType enumeration in /usr/include/gts.h.  That
definition is missing in the current Debian version of GTS (0.7.6
+darcs110121-1.1).  Ruben, are you able to upgrade gts at the moment to
get this in?

There is a version mismatch here in that both versions are labelled
0.7.6, so the dependency on the later version is not caught.  Stephane,
should the GTS version be bumped to 0.7.7 or somesuch?

Drew
