OK.

Here ‘install’ is bound to the complete match–i.e., “/usr/bin/install”.
So in effect, this clause keeps “/usr/bin/install” and appends ‘-D’,
which is why you have to patch it again in the ‘pre-configure’ phase.

It would be simpler to directly replace “/usr/bin/install” by “install
-D” in this snippet.

Likewise, “/usr/bin/strip” should be replaced by “strip” in the snippet.

In general, all the input-independent substitutions should go in the
snippet.

This is the only substitute* clause that should remain here.

Could you send an updated patch?

Thanks,
