No; some packages can only be modified one-way.  They allow incorporation
of foreign code, but they do not allow snippets of themselves to be used
in other packages, without extreme measures (such as copying the entire
package and supplying a diff that removes everything except the snippet).

I do not consider packages under such licenses to be free.
