intltool-0.28_1 seems broken--both gcalctool and gnomesession fail to build

[John Merryweather Cooper]

Something seems to be amiss in intltool-0.28_1.  Attempts to compile 
either gcalctool or gnomesession now fail.  The following fragment from 
gnomesession is illustrative (gcalctool fails in a very similar manner):

LC_ALL=C ../intltool-merge ../po gnome-session.schemas.in 
gnome-session.schemas
-s -u -c ../po/.intltool-merge-cache
Not enough arguments for mkdir at ../intltool-merge line 979, near 
"$lang or"
Execution of ../intltool-merge aborted due to compilation errors.
