Version 0.12.5 release tarball fails to compile for me on Gentoo Linux:

```
make[2]: *** No rule to make target 'dwg2ps.1', needed by 'all-am'.  Stop.
make[2]: *** Waiting for unfinished jobs....
make[2]: Leaving directory '/var/tmp/portage/media-gfx/libredwg-0.12.5/work/libredwg-0.12.5/programs'

make[1]: Leaving directory '/var/tmp/portage/media-gfx/libredwg-0.12.5/work/libredwg-0.12.5'
make: *** [Makefile:557: all] Error 2
```

On the other hand, cloning the git repo and compiling that works.
