Hi Graham,

Here some results :

        libssl.so.0.9.8 =>       /opt/csw/lib/sparcv8plus+vis/libssl.so.0.9.8
        libcrypto.so.0.9.8 =>    /opt/csw/lib/sparcv8plus+vis/libcrypto.so.0.9.8
        libpython2.5.so.1.0 =>   /opt/csw/lib/sparcv8/libpython2.5.so.1.0

        libmd5.so.1 =>   /usr/lib/libmd5.so.1
        libthread.so.1 =>        /usr/lib/libthread.so.1

I also used ldd -s to trace more in detail, and I concluded this :
The LD_LIBRARY_PATH does not intervene. All libs are resolved by using the RPATH of _hashlib.so
(which includes a path to all python libs ) and the system default search path /usr/lib.
I made tests with setting LD_LIBRARY_PATH to <empty> or even to /tmp, but still, import hashlib works fine in the python console.

Another test I made was calling python via cgi, and do a import hashlib there too :

    import hashlib

Again, no problems.

In my ptest.py, I write nothing else but :
import hashlib

And then this fails.


# Likely problem is that _hashlib.so cannot find the shared libraries it
# is dependent upon.
