If I understood your earlier reply to Jack correctly, you said 
you'd switched the linking order for gretl from "-llapack -lblas" 
to "-lblas -llapack".  If that's so, it could cause problems with 
unresolved symbols.  The point is that gretl uses no symbols from 
libblas; it uses symbols from liblapack, which in turn requires 
symbols from libblas.  The order in which the libraries are given 
to the linker must reflect this.  If you give "-lblas" first, the 
linker thinks "libblas?  We don't need anything from that, just 
move along".

This works for me, but I will check on Windows and with the 
official gnuplot 4.2.3 release.
