Comment (by tomio-arisaka):

 I looked at the commit history of portfile, but I was not able to find any
 patches to be applied to x11alpha.
 <https://github.com/macports/macports-
 ports/commits/master/print/ghostscript/Portfile>
 \\
 So I think the issue has been introduced to 9.55.0 by upstream developers.

 e.g. Ghostscript-9.55.0 has another issue as follows:
 \\
 When using the device "pngalpha", I get the same issue as "x11alpha".

 I tried to build the development version of Ghostscript.
 (9.56.0rc1: commit 8e52d5a85978c6f721ad4a3ffdf25bf18bce9d20)
 \\
 Then it works well with x11alpha and pngalpha.
 It seems that the issue has been resolved:)
