Re: [Pytables-users] import fails

[Michael H. <mh...@us...>]

Francesc - I think I answered my own question.  I have to set it in the 
environment where I'll be running.

Is there another way that this is accomplished?  I have another Linux 
system where I have pytables installed, and LD_LIBRARY_PATH is not set, 
and the import works just fine.  I installed pytables on that system (I 
think) using easy_install.

I would prefer not to have to use environment variables, because I'll be 
running my code from a cron job, where account settings are frequently a 
problem...

Thanks,

Mike
