[Numpy-discussion] Problem during build of scipy: - TypeError: can only concatenate list (not "str") to list

[Hans-Joachim Ehlers]

Given:
AIX 5.3
xlc v8
xlf v10
essl v4.2

Build and installed: numpy 1.0.4
Build and installed: lapack 3.1.1 with CCI and essl support

Task:
Trying to build scipy 0.6.0

Get the following error which seems to be numpy related:
....

Any tips ?
