Hi Meep members,
I have installed MEEP on Ubuntu and that got installed without much problem.
However, when I try to run the basic simulation provided in the MEEP
tutorial, I'm faced with the following error message:

Some deprecated features have been used. Set the environment
variable GUILE_WARN_DEPRECATED to "detailed" and rerun the
program to get more information. Set it to "no" to suppress
this message.

What is the problem? Is it to do with file permissions? Please help me out
urgently as firstly I am new to the UNIX system and secondly I've been
unable to resolve this for the past two days and I'm on a very tight
schedule.
Thanks in advance
Manan
