So I'm trying to install hiphop-php, which only runs on linux and doesn't come in package form, meaning I have to play hunt the dependency and compile the stuff.

Here are the steps I have taken so far:

Installed all of the required packages and development packages.
Downloaded and patched libevent-1.4.13 and curl-7.20.0
Downloaded hiphop-php from github.

Now I'm stuck trying to build curl, I run

configure  

and it's OK, i run

make install  

and I get

/usr/bin/ld: curlutil.o: undefined reference to symbol 'clock_gettime@@GLIBC_2.2.5'
/usr/bin/ld: note: 'clock_gettime@@GLIBC_2.2.5' is defined in DSO /lib64/librt.so.1 so try adding it to the linker command line
/lib64/librt.so.1: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make[2]: *** [curl] Error 1
make[2]: Leaving directory `/opt/hiphop/curl-7.20.0/src'
make[1]: *** [install] Error 2
make[1]: Leaving directory `/opt/hiphop/curl-7.20.0/src'
make: *** [install-recursive] Error 1

I'm reasonably confident that installing this patched version of curl is the last hurdle in the way of installing hiphop, I've scoured the web for answers but the answers seem to be either way out of date or completely irrelevant to my situation.

Can anybody help me?

Edit: Forgot to mention, I'm running fedora 16 64-bit.
