Me instale Zend Development Enviroment, para desarrollar en PHP, y tuve el siguiente error

awk: error while loading shared libraries: libdl.so.2: cannot open shared object file: No such file or directory

/home/xourge/opt/Zend/ZendStudioClient-4.0.2/jre/bin/java: error while loading s hared libraries: libpthread.so.0: cannot open shared object file: No such file o r directory

Luego de comprobar las variables de entorno y googlear un poco encontré que la solución es abrir ZDE (dentro de bin/) y comentar la linea que dice

export LD_ASSUME_KERNEL=2.2.5

(se le coloca un # delante) y listo, funcionó :D
