MarsSeed [1] filed a deletion request for python2-pkgtools [2]: Deprecated Python 2 package, discontinued in 2013. Not needed anymore. Only python2-pyg and its -git variant depends on this, and those are pending deletion. (Pyg was discontinued in 2015; it wanted to be a python-pip replacement but ultimately developer lost interest.) So I recommend to delete this obsolete package. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-pkgtools/
