The main part of the portfile is parsed, and then afterward, the variants are parsed. So the variable was not being set to its new value until after master_sites had already been set using the variable's old value.

Platform blocks used to behave this way too, but that was changed a few versions of MacPorts ago. Now platform blocks are equivalent to "if" statements.
