Check that the path for whichever user (probably root) starts up the web
server has the right environment set.
For example, if I compile apache, python and mod_python as UserA and
install to a local directory, then start the web server as root (in
order to bind port 80), it uses the wrong python (system, not newly
installed).
If I instead write a script to export PATH, LD_LIBRARY_PATH and
LD_RUN_PATH before calling httpd, then it uses the right installation.
Setting the variables in envvars and envvars-std isn't sufficient (in my
experience)
