These two goals are what I consider most important personally.

I am obviously biased; but I think the Jam language is holding us back.
Absolutely nobody know it, and anything not natively supported by the
language requires code in C, with awkward bridging.

Also, it might sound bizarre, but some aspects of Boost C++ Libraries
project are problematic. Say, Boost.Python library supports building
with Visual Studio from Cygwin shell using who-knows-what Python
library. It's hard to understand and to test, and very few people need
this funcitonality.
