Hello,

I've been working on the cyrus-sasl2 package, because it doesn't support 
plugins as it stands (pkg/19001).  One of the problems I encountered occurs 
because the configure script expects that ltconfig actually be run and update 
values in config.cache.  So LTCONFIG_OVERRIDE breaks this package.  In 
pkg/19001 I provided some patches with crude work arounds, but clearly they 
are not suitable for inclusion.

Playing around, I've tried another approach that reimplements 
LTCONFIG_OVERRIDE in bsd.pkg.mk.  It creates a ltconfig wrapper that generates 
a libtool compatable with the one normally used.  Configure is happy because 
it can depend on the side effects of ltconfig, and the libtool generated is 
compatable (virtually identical) with what would normally be invoked.

Is it likely that other software packages depend on side effects like this?

Does this sound like a reasonable solution for the general case?

The down side is that this may create a dependency between libtool and bsd.pkg.mk.

Thanks,

skd
