In Libraries section,
In general, libraries must have a shared version in the
library package and a static version in the development
package.
But, if libraries uses dlopen(3) internally, then some
programs links the static version, it doesn't work
correctly. because dlopen(3) doesn't try to resolve the
symbols in the static-linked program. in most cases, the
static version of such libraries is meaningless to be
provided.
So I think our policy needs to be added the exception of
such case.

Sure. I think describing this issue to README.Debian will be
useful for people. so I will do that.

s/-static/-Bstatic/ ?

Indeed. ok, I close this bug. if I have any question, I'll
post it to d-d.
