Please do INSTALL the package and test loading it before R CMD check.
You will get better errror messages. This has been discussed on the
appropriate R list (R-devel, not here), many times.
Since you mention -lgslcblas and no BLAS, my guess is that your shared

However, can you not obtain advice locally on R / MacOS X programming:
your address suggests that you have neighbours who are long-term
practitioners?
