Description

When building the recipe with web modules enabled, if the pip package html5lib has not been previously installed, a warning is printed in the build logs that web modules will be skipped but the package builds nonetheless.

Since the package does not match what the recipe requests, the recipe should check that the package is present before starting the build when a web module is enabled and error out.

Logs

Log not available, and the build time does not make it easy to get the logs back.

The warning is printed after the big summary where it lists back what will be built.
