[savant-devel] Size of long problem fix

[Doug Hickey]

Ruda,

Thank you for submitting the patch.  This issue only comes up when
starting a new build from CVS, so I had forgotten to revisit it.  Your
solution provides a much more informative message to the user and will
eliminate the confusing errors when building with a non-standard
$PREFIX.  The only possibilities I am aware of for specifying additional
library paths are the $LD_LIBRARY_PATH and ld.so.conf solutions you
outline in the patch.

I am currently looking into your request for a similar isClutils()
function for libaire and libsavantutils and will update you when this is
implemented.    

Thanks,
