I just did a teacup update and now I cannot load Img--I'm getting versioning error: version conflict for package "zlibtcl": have 1.2.8, need exactly 1.2.7

This is on Ubuntu, version 8.6.0 for x86_64.

Drilling down, the problem is between pngtcl and zlibtcl. pngtcl first loads zlibtcl (1.2.8 is the latest) then loads libpngtcl1.4.12.so. But the library requires zlibtcl 1.2.7.

One work-around is to do:
package require -exact zlibtcl 1.2.7
package require Img

Find out what is using the "-exact" option and stop it.

I had the same problem--just worked around it by package requiring
-exact zlibtcl 1.2.7 before doing package require Img. But someone
should fix the real bug!

okay, pngtcl/pkgIndex.tcl needs the "-exact" option when it imports zlibtcl.

NO NO NO! The -exact option is to be gotten rid of, not spread further!

okay, fix the code in libpngtcl1.4.12.so that require zlibtcl 1.2.7.

I will have a look.

In the mean time a

teacup install --force pngtcl

should solve the immediate issue. That will be a new build of pngtcl
which still has the -exact requirement, but pointing to zlibtcl 1.2.8,
and thus not in conflict.

As the version of pngtcl itself did not change it was not updated when
the other parts moved on.

Given that the issue is with a package from the AS teapot, why not
submitting a bug to our tracker at
