It's the later.

In the boost-root/tools/build/v1/gcc-tools.jam file, current CVS state, 
around lines 163-188 there's a switch for specifying the needed options 
to get version SO names working. It's this way because SO names are a 
linker feature and the linker varies per platform and not per compiler. 
This bit of code would need to acquire a new case for NetBSD, or 
possibly *BSD, as there's already an OpenBSD case.

Am I correct in guessing that the linker option for specifying the 
soname in NetBSD is the same as for OpenBSD? Namely "-soname [libname]". 
If it is I can just change the "OpenBSD" case to cover all "*BSD" cases.
