  There is another approach that involves rebuilding the libraries and
executables, but it would require fewer makefile changes than the +cdp
approach.  If you set the internal name of a shared library to an absolute
path from "/" then the linker will record that internal name when linking
against the library.  So, add a +h option to the link of each shared
library.

 ld -b -o libsum1.sl.1 +h /store/opt/kde2/lib/libsum1.sl.1 sum1.o

Then when executables and other shared libraries link with libsum1.sl.1
the linker will always tell dld.sl to look for it at
/store/opt/kde2/lib/libsum1.sl.1 even though it was linked from a build tree.
