Re: More info on libldtl failure

[Gary V. Vaughan]

Hi Bob,

Hmmm.  I think I can see why this might be... the entire deplib chain
is followed and loaded for each lt_dlopen()ed module.  Perhaps I need
to cache previous successes and failures to avoid repetition?  Or
maybe I just need to provide an option to ignore deplibs (and emulate
the old behaviour that served us so well before)?

What do you think?  Alexandre, do you have any thoughts on this?

Anyway, I will check in this fix when CVS recovers from the move to
savannah.

Cheers,
        Gary.
