I've never seen that error specifically, but here are a few things to
try:

1- Do you have PHP statically linked into your httpd executable?  If
yes, then you need to add a switch on the link line to enable loading
dynamic libraries.  I'm not sure what it should be exactly for Solaris. 
See FAQ#4.3 at
http://www2.dmsolutions.ca/mapserver/php_mapscript/php_mapscript_faq.html#4.3

2- It may simply be that libjpeg.so is not in your web server's runtime
library path.  If that's the problem then try using the --enable-runpath
configure option and rebuild your php_mapscript.so.  

3- If #2 above doesn't fix the problem, then I would suggest checking to
make sure that there wouldn't be 2 verisons of libjpeg on your system,
in which case the error may happen because the wrong copy is being
picked at runtime.

I hope that helps,
