>Description:
building lang/python27 fails with error

ImportError: No module named _sysconfigdata

(similar error as in https://mail-index.netbsd.org/pkgsrc-bugs/2013/07/19/msg052039.html)

previous version of python installed during compile time was

python27-2.7.3nb2 

once python-2.7.15nb1 had been installed, the issue went away
>How-To-Repeat:
enter /usr/pkgsrc/lang/python24 and issue "bmake" while python27-2.7.3nb2 is still installed


>Fix:
I found this problem report

https://trac.sagemath.org/ticket/24605

and the solution suggested there worked

bmake LDFLAGS="-L. $LDFLAGS" replace clean
