Apparently, the #:phases parameter has no influence on the python build system.
For instance, when adding (arguments `(#:phases '())) the package still gets built with the %standard-phases. I added a line #:phases ,phases to (define builder at line 131 of guix/build-system/python.scm. Now I can empty out the phases. But when I write something like #:phases (alist-replace 'install ... %standard-phases) apparently the %standard-phases from the GNU build system are used, as there is an error message that ./configure is not found. Could maybe someone have a look and propose a solution? Andreas
