[SciPy-user] Compile Error: error: expected `)' before 'PRIdPTR'

Hi, I am still trying to install SciPy 0.7.0 on AIX 5.3. I have managed to install NumPy 1.3.0. When I try to install SciPym I get scipy/sparse/sparsetools/csr_wrap.cxx: In function 'int require_size(PyArrayObject*, npy_intp*, int)': scipy/sparse/sparsetools/csr_wrap.cxx:2910: error: expected `)' before 'PRIdPTR'

From the reading the list I see that this problem has occurred before and has apparently been fixed.

Any ideas why this is still happening? Cheers Loris
