>Description:

See the makefile of net/pppoa:
    MASTER_SITES=           http://download.ethomson.com/download/ \
			    ${MASTER_SITE_SOURCEFORGE}
    MASTER_SITE_SUBDIR=     speedtouch
    DISTFILES=              ${SPEEDTOUCH}.tar.bz2 ${ALCATELDRIVER}

The output of "make all-fetchlist" is (amongst others)
    http://us.dl.sourceforge.net/speedtouch/speedtouch-1.2-beta2.tar.bz2

To disentangle the two distfiles and the two master_sites, use this:
    MASTER_SITES=           http://download.ethomson.com/download/:mngt \
			    ${MASTER_SITE_SOURCEFORGE:S/$/:src/}
    MASTER_SITE_SUBDIR=     speedtouch:src
    DISTFILES=              ${SPEEDTOUCH}.tar.bz2:src ${ALCATELDRIVER}:mngt

The output of "make all-fetchlist" is (amongst others)
    http://us.dl.sourceforge.net/speedtouch-1.2-beta2.tar.bz2

Note the lack of /speedtouch/ in the URL.

According to bsd.port.mk, version 1.468, around line 1917:
    .for _S in ${MASTER_SITE_SUBDIR}
    _S_TEMP=    ${_S:S/^${_S:C@/:[^/:]+$@/@}//:S/^://}
    .   if !empty(_S_TEMP)

The value of _S_TEMP is properly filled after the call. But the
call to empty() treats it as an empty variable.

>How-To-Repeat:

See example in description.

>Fix:

Try a different kind of voodoo? (that's a joke)
