[htdig] 3.2.0b2 compile problems on RedHat 7.0

[VASQUEZ_JASON]

I'm trying to compile htdig 3.2.0b2 on RedHat 7.0, but I'm running into some problems.  I am receiving the following error at compile time:

Making all in htcommon

Any ideas as to what might be going on here? it compiles find on 6.2....I'd be happy to provide any additional details that might be helpful.
