Im using CentOS server through ssh, and ran:
sudo gem install passenger
rvmsudo passenger-install-apache2-module

Passenger stops installing on:
Command failed with status (): [g++ -Iext -Iext/common -Iext/libev -D_REENTRANT -I/usr/local/include -DHAS_TR1_UNORDERED_MAP -DHAS_ALLOCA_H -DHAS_SFENCE -DHAS_LFENCE -Wall -Wextra -Wno-unused-parameter -Wno-parentheses -Wpointer-arith -Wwrite-strings -Wno-long-long -Wno-missing-field-initializers -ggdb -DPASSENGER_DEBUG -DBOOST_DISABLE_ASSERTS -fcommon -feliminate-unused-debug-symbols -feliminate-unused-debug-types -fvisibility=hidden -DVISIBILITY_ATTRIBUTE_SUPPORTED -Wno-attributes -o libout/common/libpassenger_common/ApplicationPool2/Implementation.o -c ext/common/ApplicationPool2/Implementation.cpp]

even after waiting for an hour no success, any idea what went wrong?
