Hi, just a little update on things. (see below)

Where did you change it? In CVS? This does not comile for me.
At the final of linking everything together I get:

/usr/bin/ld: Undefined symbols:
load_charmap(tree)
charmap_rep::advance(string, int&, string&, int&)
collect2: ld returned 1 exit status

I used the latest version of readline (5.1) and guile-cvs snapshot,  
because of some patches applied there to make it compile on Mac OS X.

Considering the other patches: These are some changes to plugins,  
which could be handled by #ifdef quite well. Maybe you can put them  
in the standard source code?

In the momentary package just TeXmacs, guile 1.6.4 + some patches and  
readline.
I have already made a package containing:

Ghostscript 8.5
Guile-cvs
TeXmacs 1.0.6
Freetype 2.10

and necessary dependencies but this remains to be tested a little bit  
more.

This was actually easy. Just include at recent enough version of  
Freetype. (see above)
What is strange though, is that I could not use the Microsoft fonts,  
without teTeX. Luxi worked.
Is this due to misconfiguration, or is there something wrong in the  
corresponding routines?

This sounds very good and I would appreciate such thing very much, but
to be honest I don't think I will do this. The usual problem as with  
everyone: not enough time. Sorry.
A spotlight plugin is very simple though and maybe I will write one  
myself.
