I finally got a gentoo system built and ran into the same problem as you. I think it's because of an error that happened during the build step for the Python module.
building '_OW' extension
creating build/temp.linux- i686-2.3
i386-pc-linux-gnu-gcc -pthread -fno-strict-aliasing -DNDEBUG -fPIC -I../../owlib/src/include -I../../../src/include -I/usr/include/python2.3 -c ow_wrap.c -o build/temp.linux-i686-2.3/ow_wrap.o
i386-pc-linux-gnu-gcc -pthread -shared build/temp.linux- i686-2.3/ow_wrap.o -L../../owlib/src/c/.libs -R/opt/owfs/lib -low -o build/lib.linux-i686-2.3/ow/_OW.so
i386-pc-linux-gnu-gcc: unrecognized option `-R/opt/owfs/lib'
I'm not yet certain on the purpose of the -R option or why it's not recognized. The python module is built and when make install is run, everything is installed into the correct directories. But running Python gives:
[EMAIL PROTECTED] ~/src/owfs $ python -c "import ow; print ow.__version__"
Traceback (most recent call last):
File "<string>", line 1, in ?
File "/usr/lib/python2.3/site-packages/ow/__init__.py", line 31, in ?
import _OW
ImportError: libow.so.0: cannot open shared object file: No such file or directory
For now, there's a quick workaround in defining LD_LIBRARY_PATH to include /opt/owfs/lib.
[EMAIL PROTECTED] ~/src/owfs $ LD_LIBRARY_PATH=/opt/owfs/lib python -c "import ow; print ow.__version__"
2.2p0RC-1.7
In the mean time, I'll try to figure out what's going on with building on gentoo. If anyone has any ideas as to the purpose of the -R option, where its coming from and why gcc on gentoo is rejecting it, please send along an email...

my /opt/owfs/lib directory contains:
libow.a
libow.la
libow.so
libow.so.0
libow.so.0.0.0
When I did my install (as root) I did the following:
./bootstrap
./configure --enable-python
make
make install
Output from ./configure --enable-python
Deployment location: /opt/owfs
Compile-time options:
Caching is enabled
USB is enabled
Multithreading is enabled
Parallel port DS1410E is enabled
Profiling is DISABLED
Module configuration:
owfs is enabled
owhttpd is enabled
ownfsd is DISABLED
owftpd is DISABLED
owserver is enabled
owcapi is DISABLED
swig is enabled
owperl is enabled
owphp is DISABLED
owpython is enabled
owtcl is DISABLED
I'll try installing from CVS again later tonight and see if that fixes
the problem.
