Argh, I just thought of a proper technical reason, and I think I have
spotted a possible bug in the original poster's code! Some choose to do
dlopen() when the DLL/so is in a non-standard/non-system location, as an
alternative to setting LD_LIBRARY_PATH explicitly or other link-loader
handle = dlopen("./brugs.so", RTLD_LAZY);
Seems to suggest this, However, the problem with this code, is that
the current directory (./) may not be where the user thinks it is.
I think the user meant to prepend $R_HOME/library/<package>/inst/
somehow to "brugs.so", and dlopen'ing
