distcheck failed for some mm projects

["Juan R. Garcia Blanco" <juanrgar gmail com>]

Hi,

I think since recently distcheck started to fail for (all?) mm modules.
I just checked this in:
- libchamplainmm (could have bugs)
- clutter-gtkmm (could have bugs)
- glibmm (I don't think this one could have bugs)

So I don't know if there is something wrong in my system, something
changed...

The error btw is always related to documentation, e.g.:

ERROR: files left in build directory after distclean:
./docs/reference/champlainmm-0.12.devhelp2
./docs/reference/html/classChamplain_1_1Adjustment__inherit__graph.dot
./docs/reference/html/classChamplain_1_1NullTileSource__coll__graph.md5
./docs/reference/html/ftv2plastnode.png

./docs/reference/html/functions_func_p.html
./docs/reference/html/classChamplain_1_1Scale__inherit__graph.md5
./docs/reference/html/functions_v.html
....

Best regards,
Juan.
