<div><br></div><div>In a blind/crazy idea that it might be trying to use my system PCRE (8.34-2) instead of the one in the sources directory I tried installing some of those locally to my home directory and using LDFLAGS and CFLAGS pointing to lib/include dirs where I installed them. This had no effect. And, of course, running from a clean bash instance with no shell magic applied to the environment.</div>
<div><br></div><div>The reason I want to install from source is that I require R17 to poke around, and my distro doesn't have packages for it yet. When it failed, I tried building other Rs from source, and found I was getting the same issues.</div>
