automake19 will not install

[Wyatt Lehmenkuler]

Hi,

I'm running FreeBSD 5.5-RELEASE with an updated ports system.  When I  
try to install automake19 from ports, I receive the following error.   
I have searched online how to fix, but the only answer I saw was to  
upgrade to FreeBSD 6.2 or better.  This isn't the best solution.   
Anyone know how to fix without upgrading my entire system?

Regards,

Wyatt
