Sorry, that I don't have an answer to your question, but I like to state some points about an algebraic library. A standard algebraic library has several advantages to many different tools developed by individual programmers: (1) One can benefit from the knowledge and experience of others (and of their work also, of course) (2) An open discussion process will help to avoid errors or difficulties in use (3) Programs written by others that use the library functions are more comprehensible I've got no impression of how such a library may look like and if the library is meant to be updated from time to time. Anyway, an algebraic library is important: it is nice that Haskell has the rational numbers but recently, it appeared useful for me also to have the algebraic numbers, e.g., to evaluate expressions containing roots exactly. The problem is that I'm not an expert in this stuff and thus, be very glad if such things are added by an expert. On the other hand, I'd like to add things like a linear equation solver for a non-invertible system which may help to convince people that Haskell provides more features than other programming languages do.
