I din’t found a Webinject package for Fedora 17, so I decided download the source.
For get webinject working You’ll need install these packages
yum install perl-Crypt-SSLeay
yum install perl-XML-Simple
yum install perl-Tk-ProgressBar-Mac
yum install perl-Tk-Stderr
yum install perl-Tk
Now you only will need execute ./webinjectgui.pl
