building synfig

i fallowed [tips]how to build synfig from git (fedora 16) all the way through till i got to the sh and then it said sh: Can’t open
what do i do?

Please paste link to the guide to build on fedora.

It means that the file isn’t in the folder the ‘sh’ command is invoqued.
You can safely build your own package just using the script that is shipped with synfig’s code at the autobuild folder.
