Uninstall on Centos

[Mark Taylor]

I have wkhtmltopdf 0.12.3 installed on my Centos 6.8 cPanel server.  I need to uninstall it and install wkhtml 0.12.2.1 instead (as per a Magento extension developer).  But, every attempt to uninstall (Prompt: yum remove wkhtmltopdf) just shows:

root@<myservername> [/usr/local/bin]# yum remove wkhtmltopdf
Loaded plugins: fastestmirror
Setting up Remove Process
No Match for argument: wkhtmltopdf

No Packages marked for removal

But, when I ls -l the /usr/local/bin directory, I show that it's still there:

-rwxr-xr-x  1 root root 39666344 Sep 13 10:45 wkhtmltoimage*
-rwxr-xr-x  1 root root 39745960 Sep 13 10:45 wkhtmltopdf*

And, when I do wkhtmltopdf -V it shows it's still there:

root@v<myservername> [/usr/local/bin]# wkhtmltopdf -V
wkhtmltopdf 0.12.3 (with patched qt)

How do I get rid of wkhtmltopdf and reinstall the version I need?

Thanks in advance
