Comment (by Ionic):

 Hmm, yeah, that should be how it works. I did take a look at the logfile
 again and can see gcc8, libgcc, libgcc8 and libgcc9 being added as
 dependencies (like you said transitively). I can't see any arch check
 being carried out in the log file though.

 I ran `port -Nsvtd install OpenBLAS +universal+gcc9+lapack` to get a debug
 log. Base is doing... let's say... interesting things there.

 For instance, this:
 {{{

 or this:

 {{{

 DEBUG: libgcc9 9.1.0_2 exists in the ports tree
 DEBUG: libgcc9 9.1.0_2  is the latest installed
 DEBUG: libgcc9 9.1.0_2  is active

 +
 }}}

 `-universal` seems to come directly from cctools:

 {{{
 DEBUG: epoch: in tree: 0 installed: 0
 DEBUG: cctools 921_2 exists in the ports tree
 DEBUG: cctools 921_2 +llvm37 is the latest installed
 DEBUG: cctools 921_2 +llvm37 is active
 DEBUG: Merging existing variants '+llvm37-universal' into variants

 caca + fribidi + twolame + lirc + dv + aa + smb + dts + ipv6 + speex +
 llvm37 + osd +
 }}}

 But that's not how variant mangling is supposed to work... `+universal`
 should be getting passed down to all port dependencies (and ports be
 rebuilt). Maybe base master is broken?
