23The <quote>hash -r</quote> command is to make bash forget about the
24locations of previously executed commands. If you have executed ldd
25before, bash expects it to be found in /usr/bin. Since we moved it to
26/bin, the cache needs to be purged so bash can find it in /bin when you
27want to execute it again.

31You might have noticed that we don't use the compiler optimizations for
32this package. The reason is that overriding the CFLAGS variable causes
33compilation problems. You would have to edit the Config.mk file and add
34the proper values to the CFLAGS variable and then compile the package.
35If you want to do that it's up to you. I don't think it's worth the
36trouble though. The ld and ldd programs usually are only rarely used.
