Comment(by leif):

 Replying to [comment:8 drkirkby]:
 > I would not do any of this on Solaris. The run-time linker should take
 the library from the correct directory, based on whether it's 32-bit or
 64-bit. It would be

 {{{sparcv9}}} or {{{amd64}}}

 And I wouldn't mess around with `SAGE64` and dumb flag files on operating
 systems that don't need it (which is solely for ''your'' and John P.'s
 convenience if you forget to set it on your preferred OSs).


 I don't know what you mean by ''"any of" this'', but:

 ''Does this change break anything on Solaris or other OSs?'' No.

 ''Is this change a regression on Solaris or other OSs?'' No.


 So if you want to do similar on Solaris (e.g. adding `.../lib/64` dirs if
 appropriate), please read the (Python!) code, our [comment:ticket:9864:38
 previous answers], and open another ticket for that.
