The PR starts out that way, but devolves into this:
<---snip--->
"You are right: root could not write into $PORTSDIR even though it looked
as it should, but NFS root squashing hit even though the directory had
group wheel and was group-writeable. Making $PORTSDIR world writable
addressed this.
So I guess this mainly leaves the question how we can improve the failure
mode here?"
<---/snip--->
I was trying to reproduce the NFS root squashing to reproduce the failure mode, then I could implement:
<---snip--->
"1. Change "Fetching the ports index ... index file directory
/sw/test/FreeBSD/ports not writable!"
to
"Fetching the ports index ... directory /sw/test/FreeBSD/ports not
writable; consider setting INDEXDIR."
2. Abort portupgrade at that point, instead of running into problems
later on and issuing a Ruby backtrace.
<---/snip--->
And a little later, teh following is added:
<---snip--->
3. portupgrade ignores INDEXDIR.

The discussion gets into the whole NFS root squash thing giving the impression of lousy permissions and whatnot., then asks for a change in how portupgrade fails.

Not sure if this'll help any longer, but for completeness' sake:
[root at server /usr/ports]# ls -la /usr/ports
total 60878
