[Lucas Nussbaum]

Source: sympy
Version: 1.5.1-2
Severity: serious
Justification: FTBFS on amd64

Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.

Relevant part (hopefully):
> make[2]: Entering directory '/<<PKGBUILDDIR>>/doc'
> rm -rf _build/logo
> mkdir -p _build/logo
> python ./generate_logos.py -d
> make[2]: python: Command not found
> make[2]: *** [Makefile:145: logo] Error 127

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
