The first problem I encountered was that ld couldn't find the BIO_ symbols.  Apparently they have moved to libcrypto.  I found no notice of that change in UPDATING.  Adding lcrypto to the ld command fixed that.  However, none of the programs run.  They all build correctly, but immediately exit with an error:

Well, I finally figured out what is going on.  Someone added a librss... to FreeBSD base. I use a number of other shared libraries so I guess I am going to have to test each one to see if it duplicates something new that has been added.  No mention anywhere about the new lib in /usr/src unfortunately.  My guess is that the linker used the "right" one, but the loader used the one from base which would not have my symbols in it.
