[Image-SIG] Problems with Imaging 1.0

Hi!

In SunOS aka Solaris you have to specifiy additional search paths for
shared libraries in the linker command.  This is different from the
'/etc/ld.so.conf' global system configuration you might be familar with
from Linux.  If you want to use /usr/local/lib, the relevant portion
of your $BUILD/Modules/Setup should read:

# *** Uncomment and edit to reflect where your Tcl/Tk libraries are:
        -L/usr/local/lib -R/usr/local/lib \
# *** Uncomment and edit to reflect your Tcl/Tk versions:
        -ltk8.3 -ltcl8.3 \

However you should know, that two small patches are required, to make
the Python1.5.2 source distribution go with Tcl/Tk 8.3.0.  I can send
you this patches, if you want.

But I suggest to stay with Tcl/Tk 8.0.5 for the time being.  It has
been discovered on several platforms (Linux, Win32), that under very 
rare cirumstances the combination Python/Tcl/Tk 8.3.0 may crash with 
memory violation problem, where Tcl/Tk 8.0.5 is rock stable.

I've discovered this, while running the testsuite coming with the Python
Mega Widget (Pmw) package, see <http://www.dscpl.com.au/pmw/>.  Since
this test suite makes heavy use of widget creation and desctruction,
the probability of this bug showing up in a real world app is low.

I haven't yet tried Sketch 0.6.5 on our Solaris box (it is an old Sparc 10).
Would be interesting to here, whether is will run there.

Well, you are brave to try this on Solaris!  ;-)
If you can't get further with my hints, please ask again.
