 So after some sleuthing, it turns out using the more up-to-date AGPL
 Ghostscript (as opposed to the GPL one) in pkgsrc fixes this issue.
 
 Here's `nm` on the GPL version (ghostscript-gpl, v9.05), showing
 function is exported:
 
 0000000000056870 T _jpeg_CreateCompress
 
 And for the AGPL one (ghostscript-agpl, 9.26), it is -- as it should
 be -- an undefined reference:
 
 U _jpeg_CreateCompress
 
 
 It's also worth nothing that ghostscript-gpl-9.05 has its internal
 libjpeg JPEG_LIB_VERSION defined as 80, but ghostscript-agpl-9.26 is
 at 90 (the same version that graphics/jpeg is currently at).
