Failure in installing ffmpeg

[sajesh v]

Hi,

While installing ffmpeg I am getting the following error

Unable to create and execute files in /tmp.  Set the TMPDIR environment
variable to another directory and make sure that /tmp is not mounted
noexec.
Sanity test failed.
If you think configure made a mistake, make sure you are using the latest
version from SVN.  If the latest version fails, report the problem to the
ffmpeg-devel at mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.err" produced by configure as this will help
solving the problem.
===>  Script "configure" failed unexpectedly.
Please report the problem to multimedia at FreeBSD.org [maintainer] and attach
the "/usr/ports/multimedia/ffmpeg/work/ffmpeg-2007-07-12/config.err"
including
the output of the failure of your make command. Also, it might be a good
idea
to provide an overview of all packages installed on your system (e.g. an `ls
/var/db/pkg`).
*** Error code 1

Stop in /usr/ports/multimedia/ffmpeg.


Please help me.

Thanks in advance.

Kind regards,
Sajesh.
