<br>
I'm trying to install current yt-3.3dev on Blue Waters at NCSA, using the install_script.sh route.<br>
<br>
After hacking around the fact that it has an obsolete & unsafe openssl library as the default (I needed to pass LDFLAGS/CPPFLAGS to the python build to set the -L and -rpath to the non-default usable openssl), I'm having lots of trouble getting other component
installs to work. The yt_install.log has things like<br>
<br>
<blockquote><font face="Arial" size="2">Processing dependencies for matplotlib==1.4.3<br>
Searching for pytz<br>
Reading https://pypi.python.org/simple/pytz/<br>
Download error on https://pypi.python.org/simple/pytz/: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581) -- Some packages may not be found!<br>
Couldn't find index page for 'pytz' (maybe misspelled?)<br>
Scanning index of all packages (this may take a while)<br>

No local packages or download links found for pytz<br>

</font></blockquote>
<br>
<font size="2"><font face="Arial">Yet when I run what seems like the same install by hand ($DIR/bin/pip -v install pytz) it works fine, without error.<br>
<br>
I can then re-run install_script.sh, until it reaches the next dependency and fails, etc. Each cycle takes 5-10 minutes so it's pretty tedious.<br>
<br>
***=> I don't understand why the internal-to-matplotlib-setup call to pip fails, while it succeeds when I run it by hand.<br>
<br>
<br>
A suspicion: could the CERTIFICATE_VERIFY_FAILED errors be hinting that Blue Waters has an https gateway to the outside world that rewrites SSL certificates? I don't know whether that's true. This page suggested a way to grab the needed root certificate
and point env var PIP_CERT at it...<br>

but trying that didn't help in this case. The yt-installed "pip" works fine when run by hand, but whatever matplotlib's setup.py is running still fails.<br>
