Subject: How to workaround RStudio issues
In-Reply-To: <82e98fbe-2c0f-45c5-9e3f-5a82e8c3577a@gmail.com>
An update: The RStudio bug that causes problems here is triggered by
setting "Automatically activate project-local Python environments" in
the Python global option. Unsetting that checkbox stops /usr/local/bin
from being prepended.
I've decided not to try to work around this in rgl's configure script.
