Description Matt Weber 2017-10-05 02:19:36 UTC
If building in a path that starts with /usr, the includedir=$(echo "@includedir@" | sed "s#^$prefix_build#$prefix_real#") assignment in the python-config.sh ends up having the path it processes ran through a path substitution once before this line is executed because the @includedir@ in the python-config.sh.in is set to the string '${prefix}/include'.  ${prefix} is assigned just above includedir in python-config.sh to prefix=$(echo "$prefix_build" | sed "s#^$prefix_build#$prefix_real#")

I believe we need to update the line ref below to 

includedir=$(echo "@includedir@")

Another option would be to rename the prefix variable in this file so that there isn't a naming conflict......
