+       Under RedHat Linux 5.0, if upgraded from a previous version,
+       remove the LinuxThreads packages.  This is needed because
+       LinuxThreads conflicts with the new thread support provided by
+       glibc.  Before running Python's configure script, use the
+       following commands as root (version numbers may differ; these
+       are from a stock 4.2 install):
+
+       % rpm -qa | grep ^linuxthread
+       linuxthreads-0.5-1
+       linuxthreads-devel-0.5-1
+       % rpm -e linuxthreads linuxthreads-devel
+
+       While Python only needs this to be done to allow thread
+       support to be included, the conflicts these packages create
+       with the new glibc may cause other packages which use threads
+       to fail as well, so their removal is a good idea regardless of
+       how you configure python.
+
+       Also under RedHat Linux 5.0, the crypt module now needs the
+       -lcrypt option.  Uncomment this flag in Modules/Setup, or
+       comment out the crypt module in the same file.
