Is it safe to re-install software on top of the old installation?
 

I'm currently installing a number of packages from source. Many of these packages have (optional) circular dependencies.

Once the dependency has been installed, is it safe for me to re-configure, re-make and re-install the original package into the same location as previously installed, without removing the original installed files?

Thanks guys

Yes, it should be okay to do this. I know that it is safe when
using .rpm or .deb files. Since you are compiling from source
you might need to recompile any packages that depend on the
package you are reinstalling.

Thanks
