Perfect. I personally like to keep as much as possible in the list, I just 
send big files directly to the people concerned in order to be nice to people 
with a modem.

5.8 should do it mine is quote
This is perl, v5.6.1 built for i586-linux

No. If it's in the path is ok. The feature extraction code uses image magick's 
convert tool, as David McG Squire's feature extraction code works on ppm 
only.

Oh. You're a tough guy. A missing doxygen should not cause any problems.

ignored stuff really gets ignored, so don't worry about that

This one is the important line. This is exactly the libtool stuff I was 
talking about. I have the impression that we would need to give the automake 
stuff a look and an overhaul.

There are easy and more difficult solutions.

Easy, hackish and annoying: disable all the plugin stuff I spent so much time 
on, and link statically. Involves ifdeffing and playing with --static link 
flags in the automake files. 

More difficult: make it work as it's supposed to work if you know how to use 
libtool properly. Involves deep reading of libtool manuals (well, deeper than 
I have done so far), than doing sophisticated libtooling.

Currently I have a cygwin portable at my lab with a very fresh install, so in 
my free time I will try to get at least to your state in order to be a better 
discussion partner. Then I will get back to you.

Are there any takers for helping us with this? Shy libtool gurus that do not 
dare to show? Don't be afraid!
