Without +brotli among default variants it builds:

sh-5.1# port -v installed curl
The following ports are currently installed:
  curl @8.9.1_1+http2+idn+psl+ssl (active) requested_variants='+http2+idn+psl+ssl' platform='linux 3' archs='riscv64' date='2024-09-04T19:13:11+0000'

Initially I just tried to install whatever default curl had, without specifying variants. Defaults include brotli via standard.
Since I could not install it with brotli enabled, output from the command above does not include it. How should I check if brotli is correctly detected?

Since I could not install it with `brotli` enabled, output from the command above does not include it. How should I check if brotli is correctly detected?

Evidently you'll have to start a new build with +brotli and then do something like ```

fgrep -l lbrotli -R `port work curl`

``` You should see -lbrotlidec in a bunch of Makefile files, as well as in the generated `curl-config` script . If not ans as always, the `config.log` file in $worksrcpath should give some clues as to why.
