I found that libtool shuffles the libs around:

44512: gcc -shared .libs/Evolution-DataServer-Addressbook-common.o 
.libs/Evolution-DataServer-Addressbook-stubs.o .libs/e-address-western.o 
.libs/e-book-listener.o .libs/e-book-query.o .libs/e-book-view-listener.o 
.libs/e-book-view.o .libs/e-book.o .libs/e-contact.o .libs/e-destination.o 
.libs/e-name-western.o .libs/e-vcard.o -Wl,--rpath 
-Wl,/home/patrick/evo-svn/gtk+2.0/lib -Wl,--rpath -Wl,/usr/local/evo-svn/lib 
-L/home/patrick/evo-svn/gtk+2.0/lib -L/usr/lib -lxml2 -lgnome-2 -lpopt 
-lgnomevfs-2 -lbonobo-2 -lgconf-2 -lgobject-2.0 -lbonobo-activation -lORBit-2 
-lm -lgmodule-2.0 -ldl -lgthread-2.0 -lrt -lglib-2.0 -L/usr/local/evo-svn/lib 
-lcamel-1.2 -ledataserver-1.2 -pthread -Wl,-soname -Wl,libebook-1.2.so.9 -o 
4523: IFS='     
4526: test relink = relink
4527: eval '(cd $output_objdir && $rm ${realname}T && $mv $realname 
${realname}T && $mv "$realname"U $realname)'
44527: cd .libs
44527: rm -f libebook-1.2.so.9.1.0T
44527: mv -f libebook-1.2.so.9.1.0 libebook-1.2.so.9.1.0T
44527: mv -f libebook-1.2.so.9.1.0U libebook-1.2.so.9.1.0
4529: test -n ''
4536: exit 0

So originally the library was compiled okay, but during the "relinking"
step a "-L/usr/local/evo-svn/lib" is missing in the gcc invocation
(-Wl,-rpath for that path is present!) and the wrong libcamel is picked

The questions now are: why is the relinking necessary and why does it go
