[Lucas Nussbaum]

Source: theano
Version: 1.0.4+dfsg-2
Severity: serious

Hi,

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

Relevant part (hopefully):
> make[1]: Entering directory '/<<PKGBUILDDIR>>'
> ln -s /usr/lib/nodejs/lodash-compat debian/missing-source/lodash
> #graphlib-dot.js
> make -C debian/missing-source/graphlib-dot --always-make dist
> make[2]: Entering directory '/<<PKGBUILDDIR>>/debian/missing-source/graphlib-dot'
> pegjs -e 'module.exports' src/dot-grammar.pegjs lib/dot-grammar.js
> make[2]: pegjs: Command not found
> make[2]: *** [Makefile:33: lib/dot-grammar.js] 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.
