There is something odd with this:

-- Looking for dlerror
-- Looking for dlerror - not found.
-- Looking for dlopen
-- Looking for dlopen - not found.

I'm on Linux 2.6.35-24-generic #42-Ubuntu SMP x86_64 GNU/Linux, and of
course dlfcn.h is on /usr/include and it contains dlopen:

extern void *dlopen (__const char *__file, int __mode) __THROW;

The `configure' script detects those functions alright.
