<p class=MsoNormal>This appears to defeat the install, because subsequently

Do you have MSCV/MSVS installed? You need a C compiler for "python
setup.py install" to work.<br>
<br>

</span><span style='font-size:12.0pt'>No, but I have Python installed on
another system, also without MSCV/MSVS installed, and I've imported lots of
packages without error. Is PyCrypto a special case in this regard?</span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><br>
Not overly special - it is certainly not the only python extension written
mainly in C. The majority of extensions however are just python
themselves, so don't require a C compiler.<br>

<p class=MsoNormal><span style='color:#1F497D'>Besides, I'd expect that the
install module would have the C stuff already compiled, no? <o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>Perhaps I don't have the C
