CVS: No rule to make target `insethfill.C'...

[Rob Lahaye]

Up-to-date CVS:

[...]
gmake[3]: Entering directory `/home/lahaye/lyx-devel/src/insets'
gmake[3]: *** No rule to make target `insethfill.C', needed by `insethfill.lo'.  Stop  
                             .
gmake[3]: Leaving directory `/home/lahaye/lyx-devel/src/insets'
gmake[2]: *** [all-recursive] Error 1
Any idea what's wrong?
