How to install dmd2 in centos 5.3 x64

[FreeSlave]

It's not dmd problem, it's up to ld linker and the issue is same 
for other compiled languages including C and C++. You should 
specify LD_LIBRARY_PATH variable in your system before executing 
any compiled D application. You can add export of this 
environment variable to your $HOME/.profile or $HOME/.bashrc 
depending on your system or edit paths in /etc/ld.so.conf.d or 
/etc/ld.so.conf. The other way is to copy libphobos to path where 
ld can find it by default, for example, /usr/local/lib.
