Dear Clyde, It looks like you could potentially benefit from the use of the '--minimal-toolchains' to EasyBuild. This will by default only build the required version of the software at the lowest availabel level in the current toolchain. In this case, you would still end up with 2 versions:
* M4-1.4.17 * M4-1.4.17-GCCcore-5.4.0 This is because the default is to avoid the system GCC except when strictly necessary (and in this case M4 is a dep of the binutils used to build GCCcore). There is a further option to include dummy in the minimal toolchain search, --add-dummy-to-minimal-toolchains, full details can be found at: http://easybuild.readthedocs.io/en/latest/Manipulating_dependencies.html#using-minimal-toolchains-for-dependencies Be warned that the utility of this option is dependent on the availability of the easyconfigs at each appropriate toolchain level. This is increasingly becoming the case, but is currently not standard practice for many contributors.

M4-1.4.17 M4-1.4.17-GCCcore-5.4.0 * M4-1.4.17-foss-2016b * M4-1.4.18 * M4-1.4.18-GCCcore-6.3.0 I'd like to see just * M4-1.4.17 * M4-1.4.18 What options should I pass to *not* have tool chain as part of the requirements when building a package, say Python-3.6.1-foss-2017a?
