I hope that you have resolved your issue by now.

Please note that rbibutils doesn't depend on any R packages outside base R. In fact, it is pure C within base R. The fact that in the log provided by you, stuff is loaded from RcppEigen and StanHeaders (with which rbibutils has nothing to do) suggests that on your system some compiler related paths are corrupted to look into places where they should not.

You certainly don't need to change any R settings despite what some answers here suggest. Of course, if you can install on your system a pre-prepared binary of rbibutils that will do (there are such binaries for the major Linux distributions).

As the author of rbibutils, I am always ready to consider bug reports, though this doesn't seem to be the case.
