I do not know what 'Architekt' is -- but maybe you just mistakenly assume
that you can mv(1) installations at will? And maybe you can't? Consider the
configure --prefix=/some/location/ ...
make
make install
where /some/location gets set at compile-time.
You seem to wish it didn't. But wishing alone may not make it so. In all
seriousness, these binaries may not be relocatable at will.

I'd go back to rebuilding for the target location.
