One of its developers,  Jeremy Siek, is active within
boost, but not specifically on ublas.

I believe boost as a whole is available through apt.

It is possible to make this a compile time approach. Boost.spirit
does this to allow the user to write EBNF, and generates parsers
for them at compile time (http://www.boost.org/libs/spirit/index.html)

This is beginning to sound like boost advocacy, which wasn't the point!
