[dev] questions re: horde w/ upgrade to php 4.3.2

[Rick Emery]

Seeing the writing on the wall, I decided to upgrade my Red Hat Linux 7.3 server
from php 4.2.3 to 4.3.2 and have some questions about my results (so far).

1. horde/test.php reports
   Mime Magic Support: No
despite my configure option --enable-mime-magic=/etc/httpd/conf/magic. Any ideas
about what I did wrong?

2. horde/test.php reports
   memory_limit enabled: No (in red letters)
but the explanation below it seems to indicate that "No" is actually acceptable
(in fact, it recommends recompiling PHP without the --enable-memory-limit flag,
which I did). Is it a problem for it to be disabled, or am I letting the red
wording mislead me?

3. I can no longer run pear from the command line. Typing "pear" returns "bash:
/usr/local/bin/pear: No such file or directory". If I type "sh pear" it works
as expected. I've checked environment variables, and run "sh pear config-show",
but /usr/local/bin doesn't appear in the configuration. Any idea what I've done
wrong?

Thanks in advance. The upgrade took me a while (to get the config options
right), but wasn't as painful as I expected.
