I don't want prefix 'git' and I watched this http://libguestfs.org/guestfs-building.1.html#local-files

. localenv
 ./autogen.sh \
     -C \
     --enable-werror \
     "$@"

but I cannot execute . localenv

and I saw

Note that localenv is included by the top Makefile (so it’s a Makefile fragment). But if it is also sourced by your localconfigure script then it is used as a shell script.

But I don't see any file named localenv after execute cmds and make:

./autogen.sh
make

how to solve it?
