I'll do what I can Jack, but I'm no expert in setup.py or distutils.

I can completely understand that. I've certainly accepted that by using
fink, 'all bets are off' and that I'm on my own, and that it's much more
important to have an OSX python that works on stock systems! :)

I've looked at the fink FAQ and it seems that almost all the files it wants
are installed in /sw.  The reason I started using fink is that I had
problems using the Apple compiler to get things like gnuplot compiled, and
in the process I've populated /usr/local/ with quite a few things (gnu tar
and unix python being a few of them).

That's the ideal, certainly. I'm not sure that the problem I have is due to
fink though - it's probably something to do with my 'fiddling around' with
/usr/local/ isn't it?

I have the luxury of another, clean, OSX system - but unfortunately it
doesn't have the developer tools on it (and unfortunately there's not enough
space to install the dev tools). There's a /usr/local/ directory, but
there's nothing in it.

I changed /usr/local/include/termcap.h to termcap.h-, did make clean;
./configure --enable-framework and then make. Got the same error though.


Bob sent this in:
-cut-

All they have to do is take the "source /sw/bin/init.csh" or whatever the
heck it is out of their ~/.cshrc and start up a new terminal..  I'm with
you, there's no good reason to support fink people when they're compiling
non-fink-based software.  All they have to do is turn it off to get a normal
OS X environment; it's certainly not worth your time to try and "debug"
these issues.

-bob

I've already done that Bob, there's no fink stuff in path or environment
variables or anything else. This seems to be a problem with compiling up
stuff into /usr/local/ previously.

I definitely agree it's not worth Jacks' time to try and debug fink issues.

I decided to be more pragmatic than correct about this, and changed the LN
variable in Makefile to /bin/ln. I also commented out some lines in setup.py
.... 384 - 386

                readline_libs.append('termcap')
#            exts.append( Extension('readline', ['readline.c'],
#                                   library_dirs=['/usr/lib/termcap'],
#                                   libraries=readline_libs) )

(I know this is a bloody awful 'solution')

The 'make', 'make frameworkinstall' and 'make osxapps' now work.

I now get the 'splash screen' problem with the IDE. That's ok, I can deal
with that tomorrow morning as I'm a bit knackered now.

Thanks for all the help in getting this far,
Tone
