Sorry to hear that. I'll make sure to also testcompile R in the future
before committing. Could you (if you have time, otherwise I'll check
tonight) add -lm to the flang wrapper script installed in
${LOCALBASE}/bin/flang?

flang seems to have trouble with finding its required libraries (I mean
to file a bug report with them).

On a related note: I have https://reviews.freebsd.org/D12735 up, which
upgrades the LLVM dependency to 5.0 (no version change for flang
itself).

Thanks for reporting,

Johannes
