Mahdieh just reported this problem:

She recently merged her project with the core 'maneage' branch and wanted to fully reconfigure the software environment (that was working before). But the following error showed up immediately after running './project configure -e':

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
-verbatim+

Since she had already built Maneage before, we figured it may be due to the recent [http://git.maneage.org/project.git/commit/?id=0c882a44 Commit 0c882a44] (where we check to see if Xcode is available on macOS systems). The problem is also internal to Xcode apparently, so the 'which xcodebuild' has apparently succeed.

As a fast fix, she commented the line below and the configure script was able to progress and successfully pass this step.

+verbatim+
xcode_version=$(xcodebuild -version | grep Xcode)

I had a fast search but since I am not too familiar with macOS, I couldn't find the problem. Raul, can you see what is causing this issue so we can hopefully account for it automatically (or atleast tell the users what to do to fix it)?

Alternatively, maybe we can just remove this statement: merely checking for the existance of 'xcodebuild' can be enough.

What do you think Raul? Mahdieh can run any test command you recommend to help debug this, she is in the Cc of this bug.
