"Hello Pavel,

I just tried to install hquantlib-0.0.2.0 and it fails because because:
gsl-random-0.4.3 requires vector versions < 0.8
hmatrix-0.13.0.0 requires vector >= 0.8

When I try to install an earlier version of hmatrix without this
constraint, namely, hmatrix-0.11.1.0 (still compatible with
hquantlib constraint) it fails due to duplicate instance
declarations in lib/Numeric/Vector.hs:44:10

I suspect that there is an inconsistency with Pat Perry's
hs-linear-algebra package, which is installed on my system,
together with later versions of hmatrix.

The upper bound constraint on gsl-random seems to
be the main problem, and it is not clear why this is needed
(gsl-random is not a vector package?).

Anyway, I wonder if you know about this problem and
perhaps you have found a work-around?

Thanks,
Dominick"
