[Pw_forum] Regarding the installation problem in running configure.

[Surender]

Hi,
I will suggest you to first ask the system administrator whether he had
already installed the FFTW library somewhere? If he hadn't then you can
ask him to do the same or you can install it in your home directory (I can
help with the installation).
