Makefile erroneously refers to "py36-requests1" instead of "py36-requests"
We are going to need more information to proceed. Please let us know what the revision of www/radicale/Makefile is, which OS version you are on, and which ports branch (e.g. default, 2020Q2, and so forth). And, also, the last few lines of the errorlog. Looking at the results on both amd64 and powerpc64 on the FreeBSD.org build cluster, this error is not seen. Nor do I see the problem when running "make describe" on my ports jail.
My mistake. My ports collection was out of date. Apologies.
