Is there a decent package manager we can simply use or adapt for our purposes (written in Python, of course)?<div><div>I'm guessing the answer is "No", but I thought I'd ask anyway.</div><div><br></div><div>

</div></div>Yes - this is one drawback. Also there is another issue that 'rm -rf'<br>
adresses that --download-package=reinstall can't do easily [without a<br>
proper traker and uninstaller]<br>
<br>
All --download-package=reinstall can do is install the new one over<br>
the old one. This can can still break if the new one doesn't<br>
completely overwrite the old one.<br>
<br>
One example: --download-superlu can change from installing<br>
-lsuperlu4.1 to -lsuperlu4.2. Perhaps there are other suttle breakage<br>
senarios aswell..<br>
