Hi Graeme, I recently checked in a change that should help. If the "scons" directory does not exist and SCons is importable, the installed SCons will be used instead. This is also helpful for conda builds since I want to move SCons into the conda environment. -- Billy K.

Dear All,
Back in the mists of time, one could build cctbx modules without bootstrap or conda by having the right modules available yourself - a so-called baseless install which I think is still important in X-fel land?
Anyhow, trying this with Python3 suggests that we have some special constraints which are perhaps too tight regarding module locations - for example scons -
Grey-Area p3_compile :( $ pip3 install scons Collecting scons Downloading https://files.pythonhosted.org/packages/65/41/ac58638421414acc64e26fc120c81c...

Grey-Area p3_compile :) $ make ./bin/libtbx.scons -j "`./bin/libtbx.show_number_of_processors`" ModuleNotFoundError: No module named 'SCons'
During handling of the above exception, another exception occurred:
Sorry: SCons is not available. A possible solution is to unpack a SCons distribution in one of these directories: "/Users/graeme/svn/scr" "/Users/graeme/svn/scr/cctbx_project" SCons distributions are available at this location: http://www.scons.org/ It may be necessary to rename the unpacked distribution, e.g.: mv scons-0.96.1 scons make: *** [default] Error 1 Grey-Area p3_compile :( $ which scons /Library/Frameworks/Python.framework/Versions/3.7/bin/scons
Should we require that scons is installed as part of cctbx when it is already installed on the system?
If we *do* have to have this constraint, maybe that should be checked at configure time (where it complains about six and future)
Thoughts?
In other news - the syntax changing branch referenced in https://github.com/cctbx/cctbx_project/pull/325 now compiles correctly on Python3 (note: not run, just compile but this means that it’s purpose is done) for the modules which it intends to touch and has no conflicts right now…
Best wishes Graeme
