[gentoo-embedded] Dynamic linking problem with SWIG Python bindings for Subversion

[gentoo-embedded] Dynamic linking problem with SWIG Python bindings for Subversion

[Dan C]

... at least I think that's what I've got! Any suggestions on how to fix
would be greatly appreciated.

The basic symptoms are: starting with a fresh install of Subversion
including SWIG Python bindings, I open a python interpreter:

 >>> from libsvn import _core

and the interpreter dies with:

 python: can't resolve symbol 'apr_pool_cleanup_null'

Of course ordinarily I wouldn't be importing libsvn._core (it originally
started with a Trac installation in fact) but this is as far back as I
have been able to trace the problem. Here my knowledge gets a bit hazy,
as _core seems to be a shared object.

This is what ldd says about it:

 # ldd /usr/lib/python2.4/site-packages/libsvn/_core.so
        libc.so.0 => /lib/libc.so.0 (0x4000d000)
        ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x40000000)
        libc.so.0 => /lib/libc.so.0 (0x4000d000)

        ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x40000000)
        libsvn_swig_py-1.so.0 => /usr/lib/libsvn_swig_py-1.so.0 (0x00000000)
        libsvn_delta-1.so.0 => /usr/lib/libsvn_delta-1.so.0 (0x00000000)
        libsvn_diff-1.so.0 => /usr/lib/libsvn_diff-1.so.0 (0x00000000)
        libsvn_subr-1.so.0 => /usr/lib/libsvn_subr-1.so.0 (0x00000000)
        libapr-0.so.0 => /usr/lib/libapr-0.so.0 (0x00000000)
        libm.so.0 => /lib/libm.so.0 (0x00000000)
        libcrypt.so.0 => /lib/libcrypt.so.0 (0x00000000)
        libnsl.so.0 => /lib/libnsl.so.0 (0x00000000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x00000000)
        libdl.so.0 => /lib/libdl.so.0 (0x00000000)
        libz.so.1 => /lib/libz.so.1 (0x00000000)
        libc.so.0 => /lib/libc.so.0 (0x00000000)
        libaprutil-0.so.0 => /usr/lib/libaprutil-0.so.0 (0x00000000)
        libdb-4.2.so => /usr/lib/libdb-4.2.so (0x00000000)
        libexpat.so.0 => /usr/lib/libexpat.so.0 (0x00000000)
        not a dynamic executable

Is that normal? Certainly everything configured and compiled without errors.

getting the same trouble with pygresql

can't resolve symbol: error_message

Any clues?
