2 years ago I think that the time it takes to install is longer than usual because lxml is built from C sources. On a second installation it goes faster because the built package is saved on the local pip cache.
This issue does not seem to be specific to fontbakery, as the lxml module is also a dependency of a few other projects that are also among fontbakery's dependencies, such as:
- fontparts
- babelfont
- glyphtools
- collidoscope
This is our current dependency tree, as listed out using the johnnydep tool:
