	Great.

	That is rather odd. My equivalent line is:

/bin/sh ../../libtool --tag=CXX   --mode=link /opt/icecream/bin/g++
-I/data/opt/OpenOffice/bootstrap/solver/330/unxlngi6.pro/inc/stl
-DGXX_INCLUDE_PATH=/usr/include/c++/4.5 -ldl
-L/data/opt/OpenOffice/bootstrap/solver/330/unxlngi6.pro/lib -o
DllPlugInTester DllPlugInTester.o
CommandLineParser.o ../../src/cppunit/libcppunit.la -Wl,-Bdynamic
-lstlport_gcc -lm -lstdc++  -lm

	It looks like you're missing a some -L<library path>s in there - but
surely they cannot affect this - /usr/lib will be in the compiler
library search paths (surely).

	I assume you have a /usr/lib/libdl.so (and lib64) and that you have
glibc-devel packages installed [ it would be hard not to I think ].

	Most odd; ;-) perhaps an "strace -f -e file make" output will be more
helpful, showing you which libdl (if any) it is finding.

	Thanks,

		Michael.
