The destroot can be simplified to just:

destroot {
    xinstall ${worksrcpath}/bwa ${destroot}${prefix}/bin
}

eval is not necessary because you're not evaluating any globs. 0755 is the default mode.

Using use_configure no means you need to manually ensure you're UsingTheRightCompiler and -arch flags and add a universal variant if possible—unless this port doesn't build architecture-specific software, in which case you need supported_archs noarch.

When writing sourceforge master_sites you have to be sure to avoid redirects.
