As soon as I startup the terminal (Ubuntu 12.04 LTS), I get the error message:

bash: export: `/lib/perl5/site_perl/5.14.2/': not a valid identifier

I am not really familiar with Linux yet. How do I rectify this?

EDIT:

if [ -f /etc/bash_completion ] && ! shopt -oq posix; then

    . /etc/bash_completion

export PATH=$PATH/usr/lib/lightdm/lightdm/usr/local/sbin/usr/local/bin/usr/sbin$



export PATH=/usr/lib/lightdm/lightdm/usr/local/sbin/usr/local/bin/usr/sbin/usr/$



export PATH=$PATH:/home/lib-11/Downloads/randfold-2.0/randfold



export PERL5LIB=PERL5LIB:/home/lib-11/Downloads/mirdeep2 /lib/perl5/site_perl/5$



export PATH=$PATH:/home/lib-11/Downloads/mirdeep2

mirdeep2 and randfold are executables that I wanted to run.
