OK This is really good to know.
Your Perl installation does not seem to be complete with respect to what is 
needed in 0.1.9, but for 0.1.8 it looks ok.

Plenty of input, defaults usually works.

Hmm. I think this sounds like an illconfigured or unconnected CPAN install.

It does not seem to.


OK. Here we see, the stuff is doing a make, and it seems to work up to the 
point where it wants to link to ld, a library that is not there. Now I give 
you again a snip from my last message to you.

quote
The problem is the plugin mechanism. All GIFT query engines are in fact 
plugins. So GIFT looks in LIBDIR (the dir where the libs get installed, which 
in turn depends on the ./configure parameters you give) for libs that start 
libGIFT something and end with .so . This is not portable. libtool gives you 
some possibilities to find out the name suffix of dynamic libs, and it has a 
more portable of dynamically linking than libdl, libtdl, if I remember right. 
So something that would need to be done would be to look into the details of 
portable dynamic linking using libtool and then do it the right way based on 
my code that does it the wrong way (but, I hope, would be easily changed).

So, what do we see here?

We see, that make is trying to link to libld, and there is none under cygwin. 
So now what has to be done is some work on Makefile.am's, configure.in using 
stuff described in 

http://www.gnu.org/software/libtool/manual.html , section 10.1. Would you have 
the time, stamina, and will to do that?

Oh, I think it's at least square 2.
