[NLPL Task Force (A)] NLPL modules python issue

[Stephan Oepen]

hi again, sara, andrey, all,

i believe i managed to track down this problem and was relieved to see
it is a recently introduced issue: the NLPL binaries for these Python
add-on modules had inadvertently had their set-group-id bit ('g+s')
set, which i am pretty sure was the result of a major recursive
adjustment of file permissions right before the holidays.  this bit
(probably) should be set on directories, where it will cause the group
owner to be inherited onto new sub-directories or files; but on
executable files (run by anyone but me or root), it actually caused a
loss of privileges that prevented the search for the base shared
libraries.  note to self: this was tedious to debug, because the
problem goes away when running in the scope of strace(1); it turns
out, strace(1) prevents setuid(2) and setgid(2) execution ...

sara and andrey, please try again.  i hope the NLPL add-on modules are
back to normal now?

all best, oe
