I am really clumsy: 1st, for forgetting about ldd in my "toolbox" and,
2nd, because I was already showing the environment variables in my
diagnostic cgi script and overlooked the obvious -- apache is
prepending it's own libraries to my custom path...

LD_LIBRARY_PATH=/opt/httpd/lib:/long/path/sw/lib:{REST...}

I overrode it by explicitly setting it (SetEnv) instead of passing
from the shell (PassEnv) and it works flawlessly. Now just need to
set-up modpython :-)

Merci beaucoup!

PS: btw, the Trac's installation guide puts a "CGI-capable web server"
in optional packages, does this mean that it is possible to run Trac
directly using just Python, à la MoinMoin?
