</span>I'm not sure what your exact issue is here.<br>
<br>
Is there any specific library that pjproject currently embeds that can't<br>
be trivially disabled? Do you think there is an issue with pjproject not<br>
defaulting enough to using system libraries where possible?<br>

</span>Hang on. This is RHEL. A stable platform. Why can't they just use<br>
pjproject packages and be done with it?<br>
