Why would libtool only create a static library?  Very frustrating.

This is with:

• Gentoo Linux 1.4rc3
• GCC 3.2.2
• libtool 1.4.1

I'm using the latest from CVS, by doing

$ make clean
$ ./autogen.sh
$ ./configure --with-shared --with-prefix=$HOME/Library/LWJGL
$ make
$ make install


All I get is the .la file.
