I'm using a Debian Sid distribution, regularly updated. I have the gimp-2.2 Debian package, last modification on 2007-07-13:

% ls -l =gimp-2.2 -rwxr-xr-x 1 root root 3,0M 2007-07-13 19:26 /usr/bin/gimp-2.2*

I have also gimp-2.3.19, installed in /usr/local and correctly working, but with an interface to gutenprint I cannot manage properly (I would like to enlarge a picture automatically to paper size, and it does not seem to work).

When I call gimp-2.2, I get the flash picture of version 2.3, then the following messages:

% gimp-2.2

I removed and purged the Debian package, then re-installed it, without no success. Where is my mistake? What should I try?

Thanks in advance for any help and suggestion.

I had read them, of course, and was certain to have set the correct --prefix= option to configure, since I had already did it several times, on this computer and others. Probably I forgot it this time.

Now the bad thing is done, is there a way to restore the proper situation? Where should I clean all traces of version 2.3.19?

... here the error messages, and gimp-2.2 was not working.

I got the following answer from Brendan :

Read the Release Notes for 2.3/2.4.

http://www.gimp.org/release-notes/gimp-2.3.html

And he privately suggested me to sudo a make uninstall in gimp-2.3.19.

I did it, and now gimp-2.2 works perfectly. However, I still have two questions:

- why is building gimp-2.3.19 in /usr/local not enough for avoiding confusion between the two versions? I have no LD_LIBRARY_PATH defined, thus gimp-2.2 should search its libraries in /usr/lib;

- why is the interface to gutenprint different in gimp-2.3.19, and in my opinion much less comfortable?
