Hi Ryan,
        The problem is that the Tex-Live is a static system as such. The 
binaries do seem to change for
        year to year. At least as far as I have noticed.
        
        But, many of the Tex…-packages are updated regulary. Such as 
polyglossia for example.
        There are no ports for the TeX-packages in Macports nor would it be 
feasable.
        Yet, these are working parts of the texlive-distribution. tlmgr is 
there to kept the texlive
        distribution up to date.

        Software in form of binaries do not seem to be installed. But, want is 
installed are support files
        and scripts. 

        I way I understand the way ports recognizes the a port has to be 
updated is via the portfile. I believe
        that  it is up to the maintainer to identify upstream changes and 
change the portfile.
        With texlive the support files change practically daily no maintainer 
can kept up with this. 
        
        I, also, believe it would not be feasible for MacPort to add tlmgr 
features to the ports commands.

        When one installs MacTeX one gets an "outdated" version. Then one fires 
up tlmgr(or its GUI) to get the
        latest support files if one wants. 

        That is why I suggest support for tlmgr. Of course if MacPorts checks 
if the tarballs have changed and says that
        texlive is outdated and needs to be upgraded then I stand corrected. 
but then MacPorts rebuild the entire texlive
        binaries which actually do not be to be rebuild just there support 
files 

        Maybe, some users of the Macports port of texlive can chime in and 
express their usage and if they have a need to
        kept very uptodate.

        regards
                Keith.
