make fails with lots of 
/home/cbleek/Sources/XML/expat/lib/xmlrole.c(.text+0x15d0): multiple definition of `XmlPrologStateInitExternalEntity'
/usr/local/lib/libexpat.a(xmlrole.o)(.text+0x15d0):/home/cbleek/Sources/XML/expat/lib/xmlrole.c: first defined here

After removing one "-lexpat" from the $EXTRA_LIBS in the
main Makefile, compilation works fine.

This error existed in the 4.2.3 too, There the config_vars.mk (or so) had to be modified.

Do you have more then 1 expat library installed on your computer?
 [2002-11-22 03:43 UTC] bleek at jobpilot dot de 
Yes, /usr/lib contains the original SuSE expat. But I?ve linked everything (sablotron, apache, php) with a statically
build expat located in usr/local/lib.

Shall I reproduce the problem making sure, that there is only
my expat available?

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

Given that you specify both /usr & /usr/local as the library search paths it is highly likely library confusion occurs. IMO this is not a PHP issue.
