I don't understand, what you mean here!

why should we use .la files?
(make install (in heimdal) only installs .so and .a files!)

we just link to the installed .so files and krb5-config --libs gives the
-L /path/to/my_heimdal_install/lib -lkrb5 -lgssapi

so at link time we'll get the correct libs e.g.

but then the loader will use /usr/lib/

what we could do in samba is to parse the krb5-config --libs output and
manually at -Wl,-rpath ... or something the current compiler/linker
