Re: [Python-sybase-misc] "ImportError: .../sybasect.so: undefined symbol: cs_config"

Hi Terry,

thanks for the feedback.

There are different naming conventions for sybase libraries depending on 
the version of sybase, the platform, 32 or 64 bits and if you are using 
the original sybase libraries or freetds...

I have commited a correction in trunk which hopefully should work in 
most cases:
