The default build uses plain 'sed, grep etc' with path lookups even  
though configure may discover alternatives (gsed, ggrep for instance)  
that it prefers.  If plain sed or grep are seriously brain damaged,  
then there is a chance that things will go haywire.

Bah.  What is the relative path back to your source directory?  I'll  
try to reproduce next time I am hacking on libtool...

Well, more like icepops to earthworm Jim... ;-)
