ds9-7.5_1+aqua.darwin_17 -- error building tkbltVecMath.C on mac OS High Sierra

[rprr]

mac OS High Sierra 10.13.1

I tried to install ds9. Got the error

% sudo port install ds9
--->  Computing dependencies for ds9
--->  Building ds9
Error: Failed to build ds9: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_science_ds9/ds9/main.log for details.
Error: Follow https://guide.macports.org/#project.tickets to report a bug.
Error: Processing of port ds9 failed

So I looked in the log file.

Below is shown the first error that occurs when building the ds9 port. There are a number of other math.h related errors that followed this as well such as with asin, atan, ceil, cos, cosh, exp, floor, log, log10, sin, sinh, sqrt, tan, tanh, etc.

Thanks for your help.

In the future, please Cc the port maintainers (port info --maintainers ds9), if any.

It looks like there is a newer version of the source code (7.6b8) that may be needed for macOS 10.13
