incorrect name in dependency list for vtk5

[srobertp (Spencer Patty)]

Here are the error details in the last line of my main.log file: I believe the dependency should be spelled qt4-mac instead of qt4_mac

:debug:archivefetch Active variants check for archivefetch-type install considers depends_lib depends_run: boost eigen3 flann vtk5 qhull openni

I should say that this might actually be an error in the libpcl port which requires the dependency vtk5 to be installed with the +qt4-mac but it is spelled +qt4_mac.

it comes from attempting

port install libpcl

[ryandesign (Ryan Carsten Schmidt)]

The vtk5 port has a variant called "qt4_mac". It adds a dependency on the port named "qt4-mac". This is fine and not a problem.

The variant cannot be named "qt4-mac" because the "-" symbol is not allowed in variant names because MacPorts uses that symbol to indicate the desire to disable a variant (just as the symbol "+" is used to indicate the desire to enable a variant).

There is no bug here. Install vtk5 with its +qt4_mac variant if you want to do whatever it is you were doing that caused that error message to appear.
