Seems this was due to a temporary situation in mxe-octave.
Builds fine now.

(So my guess in comment #2 was wrong)

Closing with "invalid"

For windows MXE, the installer copies openblas or refblas to libblas.dll during the install. (so there is the option of which to use)
However, back when I first put openblas in mxe, enabling openblas meant that it compiled and linked with openblas at the expense of the ref blas.
I'm in the process changing the enable-openblas option to link always against ref blas but create openblas library to match the installer option, so it wont matter which was used.

@ JohnD:
Yes, --enable-openblas

In my mail I got a response from Alois Schoegl (didn't see it here in the tracker yet) mentioning a fix; but I still see the "-lblas" flag that (but I may be wrong) should rather read "-lopenblas".

If I'm right, the proper flag can easily be uncovered using the octave_config_info command in my report.

When you created the cross build you used the --enable-openblas configure setting?

When running src/build_packages.m in a freshly installed mxe-cross built Octave-3.8.1-rc3:

In virtually none of my MXE cross-builds I see a libblas.dll, yet I haven't encountered any problems in the last year (and I sometimes do heavy computations). Intruiging. AFAICT I have MXE setup with OpenBLAS.
Copying over libblas.dll from octave-3.9.0+ (from early Dec last year) into /bin gets me exactly the same errors during installation of the tsa package.

Some of my Octave settings:

So perhaps a more robust numerical library detection is needed in the mkoctfile call in the tsa package?
