+=head2 Known Problems
+
+When compiling in PASE, there is no "oslevel" command. Therefore,
+you may want to create a script called "oslevel" that echoes the
+level of AIX that your version of PASE runtime supports. If you're
+unsure, consult your documentation or use "4.3.3.0".
+
+If you have test cases that fail, check for the existence of spool files.
+The test case may be trying to use a syscall that is not implemented
+in PASE. To avoid the SIGILL, try setting the PASE_SYSCALL_NOSIGILL
+environment variable or have a handler for the SIGILL. If you can
+compile programs for PASE, run the config script and edit config.sh
+when it gives you the option. If you want to remove fchdir(), which
+isn't implement in V5R1, simply change the line that says:
+
+d_fchdir='define'
+
+to
+
+d_fchdir='undef'
+
+and then compile Perl. The places where fchdir() is used have
+alternatives for systems that do not have fchdir() available.
