i proposed using the ltdl library a long time ago, when i was implementing
the exslt:crypto extension. at that time, there was considerable
concern expressed on this list about using ltdl in a library that was
so widely used particulary wrt. symbol conflicts. 

btw, xmlsec handles the symbol conflicts like this:

iirc, using ltdl on win32 was not pretty/straightforward either.

finally the licence issues of LGPL vs MIT, and the fact that
apache's APR DSO functions didn't use ltdl, led me to the current
implementation.
