indeed.  if you plan on compiling any extensions i would highly reccomend
doing

   export prefix=$HOME/local
   export LD_RUN_PATH=$HOME/local
   export LD_LIBRARY_PATH=$HOME/local

   make distclean
   mkdir $prefix
   ./configure --prefix=$prefix
   make
   make install
   make install-doc


doing the first three for every third party lib you intall will greatly ease
compiling and using extensions which themselves link to other libraries : like
the ruby postgres lib which, itself, uses the postgres client libs.

in fact, i wonder why mkmf would not set LD_RUN_PATH to $prefix or $libdir
when compiling?  it would avert a lot of problems...

cheers.
