in short:
#define BOOST_UBLAS_TYPE_CHECK 0

Please look at
http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?Effective_UBLAS
in section "configure ublas with macros" howto disable these checks.

Regarding those "type checks": These checks are not only useful for 
debugging the library. They also catch some misuse of functions and 
types. However, I agree that the add a lot of additional requirements 
to the data types. This is a design decision that was done long ago and 
is hardly to be removed now. The most prominent reason is that uBLAS is 
designed using 'scalars' like float and double. Thus there are a lot of 
(hidden) assumptions about availability of routines.
