Hi Chris,

If I remember well, Panther (Mac OS X 10.3) has a dlopen (see 
http://www.linuxworld.com.au/index.php?id=660010615&fp=2&fpid=1). 
Otherwise, it is provided by the "dlcompat" library 
(http://www.opendarwin.org/projects/dlcompat/), which is very small.

So you can use the dlcompat headers for pre 10.3, and use dlopen for 10.3+.

Cheers,
