If you are using minimal toolchains you should be able to just set `--use-existing-modules`

Since upgrading to EasyBuild/3.7.1 I find that when I try to build a new foss/2018a module that depends upon Python/3.6.4, it wants to install Python/3.6.4-golf-2018a rather than using the existing Python/3.6.4-foss-2018a. This then leads to conflicts between foss/2018a modules which already load Python/3.6.4-foss-2018a as a dependency. I guess that the golf/2018a version of Python has recently appeared as a new more minimal version but what is the recommended way to proceed? Can I persuade EB to use my existing Python installation, or do I need to re-install everything with a Python dependency to use the golf variant instead? (Sounds fraught with danger). Alternatively, should I revert and stick with EasyBuild/3.6.2 which seems to not have this problem?
