| make[1]: *** [install.data] Error 1

This is a race issue which is caused by
install.libs and install.data:

1) install.data needs run tic
2) tic needs libtinfo.so
3) install.libs would regenerate libtinfo.so
4) but install.data doesn't depend on install.libs, and they can run parallelly

So there would be errors in a very critical condition: tic is begining to run at the same time when install.libs is generating libtinfo.so, and this libtinfo.so is not integrity, then there would be the above error.

Let task install.libs run before install.data for fixing this bug.

The following changes since commit b4c8c74a45e386f99344cf9799eb5294ad6c9e3e:
Joshua Lock (1):

        hob: update required pygtk to 2.22.0 and gtk+ to 2.20.0
