The makefile handles it thusly,

all:	
	cd src; \
	autoconf; \
	autoheader
	mkdir -p $(BUILD); \
	cd $(BUILD); \
	../src/configure --disable-universal; \
	$(MAKE)

and so I got the following error:

--->  Configuring libreduce
Error: Failed to configure libreduce: configure failure: command execution failed
Error: See /opt/local/var/macports/logs/_Users_marbre_ports_math_reduce/libreduce/main.log for details.
Error: Follow https://guide.macports.org/#project.tickets <https://guide.macports.org/#project.tickets> to report a bug.
Error: Processing of port libreduce failed

So I did the following:

    use_autoreconf yes
    autoreconf.dir ${worksrcpath}/generic/libreduce/src

    pre-configure {
        set builddir [exec ${worksrcpath}/scripts/findhost.sh [exec ${worksrcpath}/config.guess]]
        
        configure.dir ${worksrcpath}/generic/libreduce/${builddir}
        configure.cmd ${autoreconf.dir}/configure
        configure.args-append --disable-universal
        
        xinstall -d ${configure.dir}
    }

    pre-build {
        set builddir [exec ${worksrcpath}/scripts/findhost.sh [exec ${worksrcpath}/config.guess]]
        build.dir ${worksrcpath}/generic/libreduce/${builddir}
    }
