Hi Dmitry,

thank you for sumbitting this patch! :)  If I understand it correctly, 
these are actually four different problems:

In which paths are Python and Guile installed on your system, 
respectively?  What's the preferred way to determine this on FreeBSD?

Is there a reason for you to choose `python-config' and `guile-config' 
over `pkg-config'?

It's in C++98, so how can it not be portable?  Are there additional 
language restrictions present in FreeBSD?  I tested the code with both g++ 
and clang++ and the `-std=c++98' and `-pedantic' options, and the only 
warnings I got were about empty macro arguments and commas at the end of 
an enumeration.

The intention is that Xorn shouldn't depend on GNU sed; if it does, that's 
a bug.  What problems did you encounter with non-GNU sed?

What's the preferred way on FreeBSD to address a file descriptor as a 
file?  Is there such a way at all?

The other obvious way to implement this would be to redirect the standard 
output, and let the backend output there.  I tried to avoid this as it may 
cause some messages printed to stdout to be included in the output, but 
maybe it's the better option considering portability.

How would you solve this?
