If I do 
	ldd /usr/lib/libdb.so
I get no unresolved things:
        linux-gate.so.1 =>  (0xffffe000)
        libc.so.6 => /lib/libc.so.6 (0x400d4000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

It is however not linked to pthread for some reason... Compiling & installing 
db again does not fix this problem.

However, the command line for the configure check is:
g++ -o conftest -Wnon-virtual-dtor -Wno-long-long -Wundef -Wall -W 
-Wpointer-arith -Wwrite-strings -ansi -D_XOPEN_SOURCE=500 -D_BSD_SOURCE 
-Wcast-align -Wconversion -Wchar-subscripts -DNDEBUG -DNO_DEBUG -O2 -O3 
-march=pentium4 -mtune=pentium4 -Wformat-security -Wmissing-format-attribute 
-fno-exceptions -fno-check-new -fno-common  -ldb  -DQT_THREAD_SUPPORT  
-D_REENTRANT -s conftest.cc

This lacks a -lpthread; adding this will make the the test-program compile.
