 			Hi Malte, (Tobias)

 Thank you for reporting this issue. I have ran into the same problem on =
 macOS/amd64, with an unprivileged build, and managed to find the issue.

 It is due to a patch specific to pkgsrc, which modifies setup.py by =
 adding the following line:

 > sys.path =3D [p for p in sys.path if not re.compile('^' + =
 sys.base_prefix + '/').match(p)]


 Unfortunately this effectively empties sys.path on setups where the work =
 directory is a subfolder of the destination prefix (as is the case in =
 your setup and in mine).
 In practice this prevents Python from finding its own modules during the =
 build, triggering the error you reported.

 I am not aware of a better patch than simply removing this line from =
 setup.py at the moment.

 @Tobias: any ideas?

 HTH,

 The purpose of the line is to prevent upgrade problems when setuptools
 comes with backwards-incompatible changes as happened earlier this year.

 Putting the work directory inside prefix sounds somewhat unorthodox to
 me but if you'd like you can change the regex to
 '^' + sys.base_prefix + '/lib'
 in order to avoid this specific problem [unless you name your work
 directory libwork at which point I'll wave my hands].
 I'm fine with that change but am not in a position to commit it myself
 at the moment.

 Understood.

 > Putting the work directory inside prefix sounds somewhat unorthodox to

 I believe I have a very good reason to do it.
 I regularly switch between pkgsrc branches:

 - -current for regular work on pkgsrc,
 - stable for pull-ups, and
 - frozen-or-soon-to-be-stable for tests (and building binaries ahead
   of upgrades)

 In practice this means one CVS tree with -current (everything goes in
 ~/opt/pkgsrc-current including packages and work directories, easy to
 reset and start from scratch if necessary or for tests) and one tree
 with Git (EdgeBSD) where I can switch between branches at will (to
 match /usr/pkg or work on eg ~/opt/pkgsrc-2022Q2 before the local
 system is up to date).

 I just tested your suggestion successfully on -current with
 lang/python{39,310}; I am going to commit it now.

 Thank you!
