Problems building a package for R

Not sure if this is the correct forum, but I thought someone might have had a similar issue.

I'm trying to build the package rgl for the R statistics suite on FreeBSD 8.1 on and amd64. The software compiles, but I think it is linked to the incorrect library....

Code:

Error : .onLoad failed in loadNamespace() for 'rgl', details:

I have a few versions of libstdc, but I don't know how to know which is registered as 3.4.14:

Code:
# ldconfig -r | grep std
        88:-lstdc++.6 => /usr/lib/libstdc++.so.6
        357:-lgstdataprotocol-0.10.0 => /usr/local/lib/libgstdataprotocol-0.10.so.0
        1005:-lstdc++.6 => /usr/local/lib/gcc/x86_64-portbld-freebsd8.1/3.4.6/libstdc++.so.6
        1007:-lstdc++.6 => /usr/local/lib/gcc44/libstdc++.so.6
        1014:-lstdc++.6 => /usr/local/lib/gcc45/libstdc++.so.6

I'm thinking I need to add a library to the configure options so that it can find the library it is looking for, but I'm not sure and my first attempts are not working. Any hints?

Thanks.
 
Adding the library to libmap.conf fixed the problem. Much less work than I thought I'd be doing. Thanks for the links.
