Comment 2 for bug 168657

Originator: NO

Could you please take a look what version of X11 you are running (Open
X11, and select About X11). The latest version for OS X 10.4.x is 1.1.3.
My quess is that you have version 1.0 of X11 - a panther version left over
from an upgrade from Panther to Tiger. X11 on Panther didn't supply
/usr/X11R6/lib/libXinerama.1.dylib which is what your provided log shows to
be the problem.

If you are running an older version of X11, could you please install the
version from the "Optional Installs" on the Tiger install DVD. Then run
Software Update to bring that version up to 1.1.3.

Inkscape 0.45.1 should then start okay.
