So this happens both in Windows and in Wine and the problem is that
the numpy distutils is trying to read the symbol table using "objdump"
from msvcr90.dll but it can't recognize the format:

objdump.exe: C:\windows\winsxs\x86_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.4148_none_deadbeef\msvcr90.dll:
File format not recognized

The file exists:


$ file ~/.wine/drive_c/windows/winsxs/x86_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.4148_none_deadbeef/msvcr90.dll
/home/ondrej/.wine/drive_c/windows/winsxs/x86_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.4148_none_deadbeef/msvcr90.dll:
PE32 executable for MS Windows (DLL) (unknown subsystem) Intel 80386
32-bit


But objdump doesn't work on it.
