  Ok. Well, in that case let me ask you this -- why do you
still want to keep this libraries as separate entities? From
what you've told me it seems that the best way for achiving
your goals would be to simply fold *all* of them into
lib subdirectory and just start treating them as parts
of FreeSwitch and not aliens. That would not only eliminate  
the need for 'wget' during the build process and also 
the need for endless separate ./configure ; make ; make install
sequences but will make it *much* easier to optimize 
FreeSwitch at a compiler level.

  Fair enough. But for performance tweaks this stuff matters. Now,
I would've completely understood the boundaries for my tweaks
had you have systems dependencies in mind. But from what you've
told me it looks like you really wouldn't mind privatizing all of these
libraries, would you ?

  Thanks and I'll try to be helpful ;-)


P.S. <compiler engineer hat on>
Now let me tell you -- DSOs used for dynamic *linking* are BAAAAD
(but don't confuse them with DSOs used for dynamic loading --
these are ok). So if there's any hope to get rid of them that
would help FreeSwitch on a couple of different levels starting
from stability and all the way up to performance.
