Thread:Project:Support desk/Unable to install on VPS - compilation failed and catchable fatal error/reply

Looks like it's a problem with how mod_sec is configured (its log is filled with "Audit log: Failed to lock global mutex: Permission denied" entries for almost every attempt to access something within the MW directory over HTTP/HTTPS). I'll have to ask my host for assistance with this tomorrow; I'll post the solution here in case anyone runs into this issue at some point in the future.
