missing .so extension

[Shaun Jackman]

For some reason, the .so extension is missing from the shared
library I'm building. libtool generates a file called
libpathportjni.0.0.0 instead of the libparthportjni.so.0.0.0 that
I'm looking for. I'm not sure what has changed. This was working
nicely only a week ago. When I run make, here is the relevant line
from standard out.

g++-3.3 -shared -nostdlib /usr/lib/gcc-lib/i486-linux/3.3.3/../../../crti.o 
/usr/lib/gcc-lib/i486-linux/3.3.3/crtbeginS.o  .libs/PathportJNI.o 
-Wl,--whole-archive ./.libs/libpathport.a -Wl,--no-whole-archive  
-L/usr/lib/gcc-lib/i486-linux/3.3.3 
-L/usr/lib/gcc-lib/i486-linux/3.3.3/../../.. -lstdc++ -lm -lc -lgcc_s 
/usr/lib/gcc-lib/i486-linux/3.3.3/crtendS.o 
/usr/lib/gcc-lib/i486-linux/3.3.3/../../../crtn.o  -Wl,-soname 
-Wl,libpathportjni.0 -o .libs/libpathportjni.0.0.0
(cd .libs && rm -f libpathportjni.0 && ln -s libpathportjni.0.0.0 
libpathportjni.0)
(cd .libs && rm -f libpathportjni && ln -s libpathportjni.0.0.0 libpathportjni)

I'm using automake, so there's nothing strange about my automake line:
lib_LTLIBRARIES = libpathportjni.la

I'd appreciate any help! Please cc me in your reply. Thanks,
