<p>I know that MAC OS X 10.5 comes with Apache installed but I would like to install the latest Apache without touching the OS Defaults incase it causes problems in the future with other udpates. So I have used the details located at: <a href="http://diymacserver.com/installing-apache/compiling-apache-on-leopard/" rel="nofollow noreferrer">http://diymacserver.com/installing-apache/compiling-apache-on-leopard/</a> But I'm unsure how to make this the 64 Bit version of Apache as it seems to still install the 32 bit version.</p>

<p>Any help is appreciated</p>

<p>Cheers</p>

Add this to your ~/.bash_profile which means that your architecture is 64-bit ant you’d like to compile Universal binaries.
```
```
export CFLAGS="-arch x86_64"
```
```
