Output buffer too small in latest lame 3.98.2

[Steve Hellyer]

Wondering if there is a way in Macports to request particular version  
of a port when installing?
I am running Snow Leopard 10.6.1 and have Mac Ports 1.8.1 and it is  
working fine.  I installed ports ffmpeg +lame.  Both compiled and  
installed without error.

Turns out there is a problem with latest Lame package 3.98.2 with  
ffmpeg as produces buffer errors...

Some investigation suggest that going back to 3.97 version lame  
removes this problem.

So wondering if it possible to ask for an older version.  I have  
uninstalled ffmpeg and lame and tried to install lame 3.97 using

sudo port install lame at 3.97

but I am still getting the 3.98.2 version from MacPorts using above  
method.

Appreciate the advice.
