How to use chatr to change static library path in binary?

I have solved this but now cannot recall the syntax. I want to strip or change the hard wired library paths on binaries I download from a repository. I do not have root and just want a personal install, but would rather not build every tool. I even posted the solution here once for others, but cannot find it.
Code:
$ bzip2 --help                                                                                                                        
/usr/lib/dld.sl: Can't open shared library: /usr/local/lib/libbz2.sl
/usr/lib/dld.sl: No such file or directory
Abort
$ whence bzip2
~/myroot/usr/local/bin/bzip2
$ find myroot -name libbz2.sl
myroot/usr/local/lib/libbz2.sl
$

I did something right, and now it works:
Code:
$ chatr +s enable -l /usr/local/lib/libbz2.sl myroot/usr/local/bin/bzip2

$ bzip2 --help
bzip2, a block-sorting file compressor.  Version 1.0.6, 6-Sept-2010.
   usage: bzip2 [flags and input files in any order]
   -h --help           print this message
   -d --decompress     force decompression
   -z --compress       force compression
   -k --keep           keep (don't delete) input files
   -f --force          overwrite existing output files
   -t --test           test compressed file integrity
   -c --stdout         output to standard out
   -q --quiet          suppress noncritical error messages
   -v --verbose        be verbose (a 2nd -v gives more)
   -L --license        display software version & license
   -V --version        display software version & license
   -s --small          use less memory (at most 2500k)
   -1 .. -9            set block size to 100k .. 900k
   --fast              alias for -1
   --best              alias for -9
   If invoked as `bzip2', default action is to compress.
              as `bunzip2',  default action is to decompress.
              as `bzcat', default action is to decompress to stdout.
   If no file names are given, bzip2 compresses or decompresses
   from standard input to standard output.  You can combine
   short flags, so `-v -4' means the same as -v4 or -4v, &c.

Word is that sometimes "+b disable" helps, if the files are not ELF.

This modifies your executbles in place, so it is a best practice to keep a copy of the original!

It is a cranky command, as I was getting errors about the missing library from chatr at first. Maybe just fat fingers and too much command recall! Thanks!
