The packages khal and vdirsyncer are meant to be used together. Khal is a console calendar program and vdirsyncer synchronizes CalDAV data from a remote server to the local filesystem so that khal can use it.
For some reason, the khal package is creating an "EASY-INSTALL-ENTRY-SCRIPT" (as "bin/.vdirsyncer-real") that wraps the propagated vdirsyncer executable. This means that both the khal and vdirsyncer packages contain the path "bin/vdirsyncer", which is annoying. Thankfully, they both end up executing the real vdirsyncer. Is this a common issue that we have a workaround for? I wonder if we can fix this in our package, or if I should take it upstream? I found this discussion on guix-devel relating to easy-install and path collisions, although I'm not sure if it's relevant: http://lists.gnu.org/archive/html/guix-devel/2014-12/msg00283.html Collisions! warning: collision encountered: /gnu/store/xxfyiwan4aidigk552i9pnm5z6myhk09-vdirsyncer-0.7.5/bin/vdirsyncer /gnu/store/8y78mn6ng28h0lihkfb8qasrlfydnnfy-khal-0.7.0/bin/vdirsyncer warning: arbitrarily choosing /gnu/store/xxfyiwan4aidigk552i9pnm5z6myhk09-vdirsyncer-0.7.5/bin/vdirsyncer Here is the output of `tree -a bin` from within khal's store directory: bin ├── easy_install -> /gnu/store/8y78mn6ng28h0lihkfb8qasrlfydnnfy-khal-0.7.0/bin/.easy_install-wrap-01 ├── easy_install-3.4 -> /gnu/store/8y78mn6ng28h0lihkfb8qasrlfydnnfy-khal-0.7.0/bin/.easy_install-3.4-wrap-01 ├── .easy_install-3.4-real ├── .easy_install-3.4-wrap-01 ├── .easy_install-real ├── .easy_install-wrap-01 ├── ikhal -> /gnu/store/8y78mn6ng28h0lihkfb8qasrlfydnnfy-khal-0.7.0/bin/.ikhal-wrap-01 ├── .ikhal-real ├── .ikhal-wrap-01 ├── khal -> /gnu/store/8y78mn6ng28h0lihkfb8qasrlfydnnfy-khal-0.7.0/bin/.khal-wrap-01 ├── .khal-real ├── .khal-wrap-01 ├── vdirsyncer -> /gnu/store/8y78mn6ng28h0lihkfb8qasrlfydnnfy-khal-0.7.0/bin/.vdirsyncer-wrap-01 ├── .vdirsyncer-real └── .vdirsyncer-wrap-01 Here are the contents of .vdirsyncer-real: #!/gnu/store/jdjxwh49zwnl954yk5rz09i0p0pcx42k-python-wrapper-3.4.3/bin/python # EASY-INSTALL-ENTRY-SCRIPT: 'vdirsyncer==0.7.5','console_scripts','vdirsyncer' __requires__ = 'vdirsyncer==0.7.5' import sys from pkg_resources import load_entry_point if __name__ == '__main__': sys.exit( load_entry_point('vdirsyncer==0.7.5', 'console_scripts', 'vdirsyncer')() )
