with pkgsrc that should be relatively easy :-)
No, seriously, I was refering to systems that do not support IPv6, so
there's little "danger" of this happening overnight.
pkgsrc provides a variable, USE_INET6. My question is, if it is set to no,
should rfc2553 support be compiled in nonetheless (assuming the libraries
would support it; some systems' libs do not)?
My understanding is that the whole purpose of USE_INET6 is to indicate
whether you want to compile in IPv6 support or not (regardless whether your
setup then actually makes use of it or not).
