 Priority:  Normal  |  Milestone:
Component:  ports   |    Version:  2.3.4
 Keywords:          |       Port:  python35
--------------------+--------------------------------
 I'm running OS X 10.10.5 and Xcode 7.2.1 (latest available for Yosemite),
 tested also with Xcode 7.0.1. Error message is as follows (full log is
 attached):
 {{{
 :info:build

 ./python.exe -E -S -m sysconfig --generate-posix-vars ;\
 :info:build     if test $? -ne 0 ; then \
 :info:build             echo "generate-posix-vars failed" ; \
 :info:build             rm -f ./pybuilddir.txt ; \
 :info:build             exit 1 ; \

 }}}
 This happens only with deployment target set to 10.7, any other value (say
 10.6, 10.8 or not set) works fine. It looks like some OS X security
 measure kicks in and kills python.exe, but running "sudo spctl --master-
 disable" didn't change anything. In /var/log/system.log I see the
 following message:
 {{{
 taskgated[97]: no signature for pid=25271 (cannot make code: UNIX[No such
 process])
 }}}
 All in all this looks like Xcode compiler or/and linker bug, but I would
 welcome any advice on this issue.
