'make distcheck' fails due to Automake

[Bob Friesenhahn]

I am once again experiencing problems with Automake leaving behind the
distribution files it built so 'make distcheck' fails:

ERROR: files left in build directory after distclean:
./GraphicsMagick-1.2.020040419.tar.gz
./GraphicsMagick-1.2.020040419.tar.bz2
./GraphicsMagick-1.2.020040419.zip
gmake[1]: *** [distcleancheck] Error 1
gmake[1]: Leaving directory 
`/usr/home/bfriesen/build/GraphicsMagick-8-static/GraphicsMagick-1.2.020040418/_build'

% automake --version
automake (GNU automake) 1.8.3

This is under FreeBSD 5.X.

What steps should I take to find the cause of this problem?
