calendar errors

I just installed the calendar package on a freebsd box with apache php mysql and some of the pear stuff is working because I have phpwebsite installed and it uses pear. I tried a test script and got the following errors Warning: getengine(Calendar/Engine/UnixTs.php): failed to open stream: No such file or directory in /usr/local/share/pear/Calendar/Calendar.php on line 80 Fatal error: getengine(): Failed opening required 'Calendar/Engine/UnixTs.php' (include_path='.:/usr/local/share/pear') in /usr/local/share/pear/Calendar/Calendar.php on line 80 these files and paths are there and are spelled the same way with caps but not being found for some reason any help would be appreciated
