Python core libraries problem in archlinux
Greetings
While instaling the core libraries for ROS and following the page instructions http://ros.org/wiki/fuerte/Installation/Arch, I have some comments (if this is not the best place to put this, I appreciate if someone can lead me to the right place)
In the prerequisites part, there is no pcl package, this doesn't exist in arch official repos, only in aur, so this command should be removed.
The packages mantainer removed the swig-wx package that uses ROS specific implementation, and there are some issues compiling FLANN (Archlinux only related issue but is better to put it out in the open).
When making the core libraries, the cmake command gives error about not finding python-empy even when it's installed. This can be fixed if you force cmake to use python2 instead of python3 (or simply python in Archlinux), which I did making a simblik link to an auxiliar folder and putting it in the PATH.
ln -s /usr/bin/python2 /usr/local/bin/alt/python
export PATH=/usr/local/bin/alt:$PATH
This python error is because the syntax used in the command, which python3 doesn't support. Being that python3 isn't supported in ROS in general, the best solution would be to use python2 in all the process and make the user aware of this even at this stage.
Only reporting about fuerte experience so far.
