Thanks for letting us know. You will need to make up the lost time somehow.

You need to take a look at the log and the directories left after the build in
the build tree. The names used need to match up or the RSB will not be able to
find the installed tree to copy to the prefix.

Note, most packages support the `DESTDIR=` make option to `make install` to
control installing to a location that is not the specified prefix. The RSB does
this to stage packages that form part of a vertical stack.

Is there an EPICS install pass in the build?
