virtualenvwrapper uses GNU extension like \s in sed regexes instead of POSIX [[:space:]]. This makes it fail on non-GNU systems like FreeBSD.
Possible solutions:
- replace GNU extensions with POSIX ones
- check for the presence of GNU sed by the name of
gsed (which is available in packages on Free- and OpenBSD) and use that if available
