curses, python20/152, RH70/62, postgresql problems

[dubal at my-deja.com]

Hello!

We are trying to develop a business application for dumb terminals
using python, curses and postgresql.

First we tried to install the Beopen Py20 rpm on RedHat 7.0. It looks
for some old libs and doesn't install.
We then tried to compile Py20 source on RH7. It gives some LONG_BIT
error and stops.
We then renamed /usr/bin/gcc to gcc.nogo and renamed kgcc to gcc and
tried to compile py20. Got same error.
Has anyone found out a way to get py20 to work on rh7?

We then read curses howto from python website and started developing
using the RH7's stock python152.
We found following problems:
1. Color cannot be used because the required vars are not available.
2. pads cannot be used as mentioned in howto.
3. getstr(x,y,len) does not allow the 3rd argument (length)
Can anyone please suggest any solutions to these?

We then abandon rh7 and go to rh62 with beopen py20 rpm installed.
getstr works fine. Color vars are available but we could not get the
color to work.
Latest (7.0.3) postgresql rpms are also installed on this machine.
This includes postgresql-python rpm supplied by postgres site.
When we try to connect to postgres from python, it produces following
warning:
Python C API version mismatch for module _pg:
This python has API version 1009, modules _pg has version 1007
How to fix this?
It seems to work after this warning. We checked the pygresql site. It
says their next version will have py20 compatibility. Do you think it
is ok to use _pg with the version mismatch?

I read somewhare that curses do not have colors, ncurses do. I see that
ncurses is preinstalled on rh. Does python have its own builtin curses
or does it use the one from separately installed rpm?
How to get the color to work?

Thanks for reading and TIA for any replies.
