I compiled the recent numpy from svn on gentoo-amd64, since then I often get
the error message:
RuntimeError: FATAL: module compiled aslittle endian, but detected different
endianness at runtime
Of course AMD64 is little endian, and array's byteorder is little endian by
default.

been applied ( :( ).

She did set FC to g95 before,

It's left in a corner. The use of dateutil.parser comes from
matplotlib.
I actually figured out a workaround with converters, since my missing
values are , ,ie., irregular number of spaces and the
values aren't stripped of white spaces. I just define {# : lambda s:
float(s.strip() or 0)}, and I have a loop build all of the converters,
but then I have to go
