No it is not. Do you see the /usr/local/lib/R/lib here? The trailing R/lib is what Martin and talk about. It means ldd / ldconfig does not know about it -- if you do `ldconfig -p | grep libR` chances are you see nothing.

You are distributing shared libraries that | aren't meant to be shared (outside of R)? But they are. And I gave an example. A wrong one though. | I will just patch the FreeBSD port. Please do. You currently are the only one with an itch to scratch, and everybody else is busy. If / when you have a patch which puts a token soname onto every shared library produced [ internally ] by R feel free to offer it to R Core. As Martin told you, so far there is no reason to take it but maybe that will change. Or not. Consider eg this: edd@max:~$ locate Matrix.so /usr/lib/R/library/Matrix/libs/Matrix.so /usr/local/lib/R/site-library/Matrix/libs/Matrix.so /usr/local/lib/R-devel/lib/R/library/Matrix/libs/Matrix.so edd@max:~$ I have three versions of Matrix.so. And still not problem. The third one only enters for R-devel, not R. The first two are distinguished by R itself _by virtue of different paths_ just like Martin and I told you. And _no_ other program on my system knows about Matrix.so: edd@max:~$ ldconfig -p | grep Matrix.so edd@max:~$ ldconfig -p | wc -l 2814 edd@max:~$ ldd / ldconfig do NOT know Matrix.so -- as I told you before -- despite the fact that they know thousands of other things on this (development) machine. All that you said or quoted about soname is fine and handy, and we all respect it __for public libraries like libpng or libxml2. R is different. So if FreeBSD has a problem with that you may indeed have to work around that on the FreeBSD side of things.
