@Isles487, look in the "pidgin_build_2.6.2" folder in the 4shared link with my installation files. It has a newer m4 and autoconf (which worked at least to build pidgin). autoconf-2.63-ps2.tar.gz and m4-1.4.13-ps2.tar.bz2 are the versions. I haven't tried compiling PHP myself, but danielb has - check out his 4shared link (in thread). Let me know if you found anything particularly confusing with the installer so I can fix in the next version. There are little changes like the backspace key not working in the dillo browser and youtube scripts which were not working in the March 2010 version, but have been fixed in a yet to be released version.
