This is not static library. It is import library for DLL, therefore it's
natural that your library links to DLL. The static library would be named

   "libboost_regex-vc90-mt-gd-1_38.lib"

I think the declarations in site-config have to be appropriately modified. E.g:

        searched-lib boost_regex:
          : <link>shared:<name>boost_regex-vc90-mt-gd-1_38
            <link>static:<name>libboost_regex-vc90-mt-gd-1_38 
          ;

Note that using <name> conditionally as above requires that you use shared-lib as
opposed to lib, as otherwise auto-detection of 'this is actually searched lib'
might not work. 'searched-lib' is the recommended spelling anyway now.

Does this help?
