x11-fonts/libXft Strangeness

[Dave Tweten]

When I build x11-fonts/libXft on a T23 ThinkPad that has been updated 
about once a week, I have no problems.  On two others that weren't 
updated for a period recently (May, I think), attempting to make libXft 
results in the following failure.

At first I thought the problem was with the libexpat build not creating 
/usr/local/lib/libexpat.la.  That's not the problem.  That file doesn't 
exist on the machine that can build libXft either.

Can anyone shed some light on why /usr/local/bin/libtool15 requires 
/usr/local/lib/libexpat.la on two machines but not on the third (more 
frequently updated) machine?

Libtool15 is not my favorite kind of reading material.  Any help 
avoiding the need to read and understand it would be welcome.
