In fact it was a typo, this is an external package developed by
Nicolas Cellier : http://www.squeaksource.com/Smallapack.html
Sorry, not integrated with SciSmalltalk at the moment.

Hi Ben,
Smallapack would definitely have its place in SciSmalltalk.
It's currently using FFI because that's what existed at the time of writing.
But it would be interesting to rewrite the foreign call with NativeNoost.

The bad news is that there are a lot of entry points!
The good news is that most of the foreign calls were generated, so a slight adaptation of the generator for using NativeBoost instead of FFI should do the trick...
Or we can attempt an automatic translation FFI->NativeBoost (the range types used in LAPACK is quite limited, so it seems feasible). Does it exist?

The second point is that some LAPACK functions take more than 15 parameters, so a Compiler hack is necessary to transform these calls into a single parameter array at the Smalltalk level.
The hack exists but is written for the Old Compiler.
No problem in Pharo 3.0.
For Pharo 4.0, it's possible to port the same principle to the New Compiler, but at first glance it's far less simple (many more classes to modify/derivate).
Or in the interim, make the Old Compiler a separate package and declare a dependency on the Old Compiler...
