Thanks for posting. As it is said on the info page, I am the author of php5 package
I made 5.3 as cgi/fcgi mainly because I needed it for my integrated system, but since I still do have my build env accessible, I will release 5.4, 5.5, 5.6 versions in a few weeks, after I come back from my vacation.
Stay tuned
BTW: Every next release breaks some apps because of code-level incompatibilities, so updating 5.3 to 5.4 or any newer version may be undesired in some cases.
