I am not sure what kind of problems you are having. Here's a canonical
way to do this:

1. Grab Boost 1.44 (using a corresponding tag). "svn export" is OK.
2. Import it into your local SVN repository, at ^/vendor/boost
3. Create a local copy, at ^/trunk/boost
4. Make changes as you like.

Then, when 1.45 comes out, you do this:
1. Grab Boost 1.45
2. Import it, again to ^/vendor/boost
3. Merge from ^/vendor/boost to ^/trunk/boost

SVN has a script to do imports of external source base. Have you
tried this procedure?

In fact, even if you prefer working with the other version control system,
it's pretty easy to handle Boost:

1. Use git svn to mirror ^/branches/release
2. Create a branch, hack away

For each next release:
1. Use git svn to mirror all revisions on ^/branches/release for the next release
2. Use git rebase to reapply your changes.

This is totally straight-forward. I am sure that Mercurial must have
something similar?
