When building GNU PSPP I see this:

This patch fixes it. It seems that gnulib-tool.py never respected the
directory passed with --doc-base.

PSPP doesn't use the bootstrap script, and running make without a
target will fail with GNULIB_TOOL_IMPL=sh+py because of some *.png
files.

This seems to work:

       env GNUMAKEFLAGS="" GNULIB_TOOL_IMPL=sh+py make -f Smake prep_ph
