Hello, I have installed postgresql 9 on fedora 14 having python 2.7. Now created plpythonu language in my database and created a simple function to calculate sum of two variables. while importing math libbrary and executing the function i got the error PL/Python: ImportError: No module named cmath tried to search help for this error on net and tried various things but nothing solved this. What can I do to solve this error. I can still work from python interpreter directly. Thanks in advcance.
