@maid: that's unfortunate, but it doesn't mean the software can be built without it.
If you need assistance with the build failure, perhaps open a thread on the support channels for your distro and provide details. Alternatively, there is a python2-bin package which you can use as an alternative to compiling python yourself. To that end, there are also -bin packages for palemoon in the AUR which you can use as an alternative to compiling the browser yourself.
