ALT Linux Bugzilla – #31416

dot2tex-2.8.7-alt1_11
python-module-pyparsing-2.0.3-alt1

dot2tex fails to run because of an unsatisfied import from python-module-pyparsing .

(Of course, this problem could be prevented if RPM's automatic reqs/provs for python modules were more fine-grained: listing all the individual imported and exported names;  but this is heavy, it's like set-versions for C libraries. I don't know whether some minimal required versions of python-modules can be automatically extracted from the code. Can't this be checked when re-compiling the broken package. E.g., when re-compiling dot2tex in Sisyphus, shouldn't this error be detected?)

For example, when doing "make" in https://github.com/rominf/latex-g7-32 (which calls dot2tex; mentioned in https://bugzilla.altlinux.org/show_bug.cgi?id=31414 ), the following errors happen:
