Python itsttol became broken by libxml2 missing USE flag

Message

I was trying to build media-gfx/openscad-2025.05.01_pre-r1 which depends on /usr/bin/itstool ( dev-util/itstool) which is written in Python and, in turn, imports libxml2.

I received an error message during the install phase of openSCAD:

I determined the problem was the itstool required the libxml2 module and my libxml2 (dev-libs/libxml2) did not have the USE flag "python" activated. So I added the use flag "python" to dev-libs/libxml2:

Code: Select all

cat /etc/portage/package.use/libxml2 |grep -v '#'
dev-libs/libxml2 python

and re-emerged dev-libs/libxml2. After that, I was able to successfully install openscad. The problem was my system which was recently updated as of 12/04/25 with 310 upgrades and everything seemed fine, but somehow my itstool became broken.

I have the openscard build tree preserved, but that really is not the problem, it is just symptomatic of another problem which I do not know how to categorize.

Should I dismiss this as something unique to my machine, or pursue trying to determine where the failure occurred so others do not run into the same problem?

Newer itstool doesn't need libxml2[python]. We need to see emerge --info and the itstool, libxml2 versions.

I suspect you hit an issue where itstool[python] was unsatisfied because of a Portage bug (which is known but difficult), but it can't happen again in future for newer itstool (which is stable since bug 966478) because that dependency happens to be gone.

Anyway, there's nothing to do on your end. You should sync though and do a world upgrade.

Thank you. Sam. Proceeding with upgrade: 295 packages (on a Plasma desktop).
