Here's another example of $prefix/lib (in this case /home/mjl/tools/lib)
being "lost" in the link line:

/bin/sh ../../libtool --mode=link gcc  -g -O2   -o libtclmatrix.la -rpath
/home/mjl/tools/lib -version-info
 6:0:1 -rpath /home/mjl/tools/lib -no-undefined -L /home/mjl/tools/lib
-ltcl8.3 tclMatrix.lo matrixInit.lo 
 
rm -fr .libs/libtclmatrix.la .libs/libtclmatrix.* .libs/libtclmatrix.*

gcc -shared  tclMatrix.lo matrixInit.lo
-L/home/mjl/dev/plplot/latest/bindings/tcl -ltcl8.3  -Wl,-soname -
Wl,libtclmatrix.so.5 -o .libs/libtclmatrix.so.5.1.0

Not good, as the version I have of tcl8.3 under $prefix/lib is the one
I want to link against, and this line causes the tcl lib under /usr/lib
to be used instead.
