today, when i was auditing what needs to be updated, i came upon this:

autoconf-2.13.000227_5              <   needs updating (port has 
2.13.000227_6)
autoconf-2.53_3                     <   needs updating (port has 2.53_4)
autoconf-2.59_2                     <   needs updating (port has 2.59_3)
automake-1.4.6_3                    <   needs updating (port has 1.4.6_4)
automake-1.5_3,1                    <   needs updating (port has 1.5_4,1)
automake-1.9.6_1                    <   needs updating (port has 1.9.6_2)

how did i manage to get so many of these 3 things installed?  can i assume its 
safe to remove all but the highest version?

thanks,
