Webalizer quit after Plesk update - shared library files went missing!

[visualsoda]

Hello everyone,

I recently updated Plesk using the upgrade manager and since then Webalizer has ceased running.

"/usr/bin/webalizer: error while loading shared libraries: libXpm.so.4: cannot open shared object file: No such file or directory"

Here's what I've found out so far...

ldd /usr/bin/webalizer returns:

libgd.so.2 => /usr/lib/libgd.so.2 (0x40018000)
libpng12.so.0 => /usr/lib/libpng12.so.0 (0x40052000)
libz.so.1 => /usr/lib/libz.so.1 (0x40077000)
libm.so.6 => /lib/libm.so.6 (0x40088000)
libnsl.so.1 => /lib/libnsl.so.1 (0x400aa000)
libdb-4.2.so => /lib/libdb-4.2.so (0x400bd000)
libc.so.6 => /lib/libc.so.6 (0x40190000)
libXpm.so.4 => not found
libX11.so.6 => not found
libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x40296000)
libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0x402b4000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
libpthread.so.0 => /lib/libpthread.so.0 (0x40319000)

/usr/bin/X11R6 contains three subdirectories, bin, man and share. /bin and /share are empty and /man contains 8 more subdirectories named man1 through man8, all of which are empty.

This is a live VPS with client sites on it.

Question 1: does anyone have any suggestions as to how I can replace the files that went missing after the Plesk update?

Question 2: there seem to be a lot of people having problems after using the upgrade manager in Plesk, is it generally a good idea NOT to use it?

Thanks so much in advance,
