After a couple of hours of work, I finally got PHP to compile with
pfpro enabled. You can see the output of phpinfo at
http://www13.karatedepot.com/catalog/test.php. However when I call
prpro_init() I get:

"Fatal error: Call to undefined function pfpro_init() in
/home/sites/site1/web/catalog/test.php on line 4" (as seen on the
bottom of the info page)

Any ideas?

Thanks,
