97 | WARNING: If you are using ksh to run the Configure script, you may find it |
98 | failing in mysterious ways (such as failing to find library routines which |
99 | are known to exist). Configure seems to push ksh beyond its limits |
100 | sometimes. Try using env to strip unnecessary things out of the environment |
101 | and run Configure with /sbin/sh. That sometimes seems to produce more |
102 | accurate results. |
