If you use libtool for linking, and the libltdl.la file is installed, 
then dependencies are taken care of automatically. If you're not using 
libtool for linking, then you're making a mistake. The point of using 
libtool and libltdl is to avoid having to check for other 
system-specific dependencies. Checking for libdl is (a) redundant since 
libtool's configure script would have already looked for it and (b) 
insufficient since other platforms may use some other name for their 
dynamic linking support library.
