The jamroot.jam file in v2 (origin/master in git) is trying to install this file which is not in the src dir but at the root:
$(SELF)/src/boost-build.jam
This change is what caused it:
SHA-1: d3015e3ea44cb7cd7d9dfd9e455a653167ccf87a
* Update relative paths.
Should boost-build.jam be moved into src also?
Thanks,
Chris
