I get this error when I run php (or php script). $ php php: error while loading shared libraries: libhistory.so.4: cannot open shared object file: No such file or directory My readline was just upgraded to readline 5.0 which contains libhistory.so.5 However, I can run othe programs that need readline 4 like irb from ruby or python.

Did you do a revdep-rebuild like the readline ebuild tells you? That (reemerging php, that is) fixed this for me.
Of course reemerging php shold fix it. But in some distributions the library versions that are binary incompatible have different package name. So it is known that the other packages need updating as well if they depend on the old name. OK, perhaps I should save the output of emerge -u world so that I can read it later.. if it was said there i could know :)
marking as invalid since you found it was your own problem, not a problem with PHP. look in make.conf for the logging options ;-). portage automatically re-building things broken by upgrades of libraries is in the works I'm told, but we shouldn't expect it for at least 6 months. There are still many other systems out there that don't have a similar feature, and haven't ever had one (eg IRIX's inst tool, now without this functionality for 8+ years).
