try setting LD_LIBRARY_PATH to the location of libgimp (directory
containing lib) and see if that helps

for example

  export LD_LIBRARY_PATH=/usr/local/lib/
  ruby a.rb

and see if you still get the error.  if dlopen fails then there is
some other issue.  make sure the lib is actually there - if it this
works then massaging LD_RUN_PATH *should* work.
