dosbox is only available for 32-bit (i386). On your OS version, software builds 64-bit (x86_64) by default. Therefore, anything that is 32-bit only and has dependencies must install those dependencies universal (32-bit and 64-bit) on your system. You have disabled universal building by setting universal_archs to empty, therefore you cannot install dosbox. If you want to allow universal builds, remove the line "universal_archs" from macports.conf to let the default value (x86_64 i386 on your system) take effect. The compilers in Xcode on your OS version cannot compile for ppc so including ppc in universal_archs won't work.
