Yes, because etc/ldpaths doesn't get configured properly so I edited
manually. I should fix the configure script to identify all the environment
variables properly first. It may be causing problems further along.

Indeed, I got that far myself in the meantime.

                                   Filename Dynamic.Lookup
base                                   base          FALSE
tools /Store/d2/library/tools/libs/tools.so           TRUE

data frame with 0 columns and 0 rows

For now I will keep digging into what dyn.load() is doing and why the
symbols are missing. Any tips are appreciated.
