On further research, http://www.gnu.org/licenses/gpl-faq.html#IfLibraryIsGPL
seems to imply that linking a program to a GPL library (even for personal
use) means the program must be GPL.

This seems like a contradiction.

So would pseudocode like:
if ( lib = dl_load("libreadline") )
	//Use libreadline code
	//Use internal stub
	lib = dl_load("libreadline_stubs"); 

be a way around this?  Especially if the program only Suggests: libreadline?
