Checkinstall has been dropped from openSUSE because it doesn't work
anymore. Checkinstall's trick is to load a library via LD_PRELOAD
that redirects all functions dealing with files. Now for installing
a package you need to be root and for programs running with root
privileges the dynamic loader ignores LD_PRELOAD as this would
otherwise be a huge security problem.

The behaviour is: For programs being setuid root, LD_PRELOAD is
ignored - or more exactly:
/* The LD_PRELOAD environment variable gives list of libraries
separated by white space or colons that are loaded before
the executable's dependencies and prepended to the global scope list.
If the binary is running setuid all elements containing a '/' are
ignored since it is insecure. */

That suggests that a replacement could be constructed by symlinking from
the current directory to the elements of LD_PRELOAD and substituting
those local, slash-free symlinks for the names in the original
