Open up the file and find the functions listed inside.
The will look like:
function functionname(arg1,arg2,etc) {
}
add code around them so that they look like:
if (!function_exists('functionname')) {
function functionname(arg1,arg2,etc) {
}
}
do this to the abs2rel and rel2abs functions in those two files. We'll be releasing an update to framework builder to address this issue as well as a handful of others reported since the release. That update should be available in the next week or two.
