I’m not too familiar with the racket build process, but I think it built the base/minimal racket, failed building packages:

> raco pkg install: version mismatch for dependency > for package: 2d-lib > mismatch packages: > base (have 6.5.0.7, need 6.6.0.3)

Windows 10, Visual Studio 2015

andreiformiga: Thanks for checking! I should have been clearer that it’s the rktio branch of the repo; I haven’t used the main branch in a while, which (based on the version number) seems to be what you built. Also, I’m going to count Windows 10 as a common OS distribution, and I’m checking that one directly. :slightly_smiling_face:
