ERROR after applying patch CSCtj01051: solaris9 CS 3.3 - LMS 3.2

I installed a couple of LMS 3.2 point patches on a solaris 9 box. Afterwards the LMS did not started any more. DCRServer hang in "Waiting to initialize" and Apache failed to run. Also a couple of other processes failed (attached pdshow).
Troublshooting this I found a line in dmgtd.log which says web_server misses libm.so.2;

I have installed cwcs33-sol-CSCtj01051.tar which updates Apache to 2.2.16 (and already had the patch for CSCtg46847 installed - which is a prerequisite).
As I could not find  libm.so.2 in /usr/lib I did ldd on web_server, which gave me:

bash-2.05# ldd /opt/CSCOpx/MDC/Apache/bin/web_server

so beside libm.so.2 everything seems to be in place - but it seems not to be recognized by /opt/CSCOpx/MDC/Apache/bin/web_server

Also libm.so.2 seems to be for solaris 10 (according to some threads on the web) and thus I ask myself if cwcs33-sol-CSCtj01051.tar is really intended for solaris 9...

And also, I ask myself how I can get LMS running again ...

Wow, that's not good.  I am fairly certain that development assumed libm.so.2 would be present on "Solaris" and not that it was a Solaris 10 version of the shared library.  I'm going to file a bug against this.  In the meantime, this trick should get you running again:

ln -sf /lib/libm.so.1 /opt/CSCOpx/MDC/Apache/lib/libm.so.2

thank you Joe for filing the Bug.
When I observed the issue I was quite at a loss and it took me a while to find the reason.
I created a softlink on libm.so.2 but this didn' t solved the issue. ldd /opt/CSCOpx/MDC/Apache/bin/web-server showed that this library was now found but some other still not.
The reason was a bit strange and I am not sure if my troubleshooting steps caused it (e.g. re-applying the patch) or if I was just unconcentrated as "it was late in the evening ...."
Finally I found that the other library files which comes with LMS (libaprutil-1.so.0, libexpat.so.0, libiconv.so.2, libapr-1.so.0) and are stored in NMSROOT/MDC/Apache/lib have had a byte size of 0;
Happily, I had still another server running and could copy those files to the local server, restarted dmgtd and got it back running
So I am not sure if the patch just introduces libm.so.2 or if it also has some impact on somee other libraries in  NMSROOT/MDC/Apache/lib.
I will update the other server in the next 2 or 3 weeks, then I can tell....
