I can't get this to build. I manually did the autoreconf, but now configure fails:

```
checking whether to build static libraries... yes
./configure: line 11456: syntax error near unexpected token `ON'
./configure: line 11456: `DX_DOXYGEN_FEATURE(ON)'
```
Any idea why its not working for me?

autoconf is 2.61, do you require some specific version?
