Hi Rolf & All, I haven't built R in a while, but my general expectation of an autotools based build & install would be that the default prefix is /usr/local, rather than /usr. So I'd expect the shared libs in /usr/local/lib, /usr/local/lib64 etc.
I also have a recollection that I once installed Rstudio for some MOOC, and ended up putting a symlink in somewhere like /usr/lib* , because Rstudio was only available as a binary with the location of the shared lib hard-baked into it. Depending on your <various flags> this may be irrelevant, apologies in that case.
