Thanks for your messages on subversion and testing. This is very helpful material. I set up a /devel directory, because my distro came with an empty /opt directory and I figured I'd better not put any junk there. liblouis installed in /devel with no problems. When I tried to install liblouisxml there it seemed to be looking for liblouis.h in /user/include instead of /devel/include so I think I need to set an environment variable for the include path. What is the name of this variable?
