DISTNAME is the name of the port as called by the authors of the software. DISTNAME defaults to ${PORTNAME}-${PORTVERSION}, so override it if necessary. DISTNAME is only used in two places. First, the distribution file list (DISTFILES) defaults to ${DISTNAME}${EXTRACT_SUFX}. Second, the distribution file is expected to extract into a subdirectory named WRKSRC, which defaults to work/${DISTNAME}.

Note: PKGNAMEPREFIX and PKGNAMESUFFIX do not affect DISTNAME. Also note that when WRKSRC is equal to work/${PORTNAME}-${PORTVERSION} while the original source archive is named something other than ${PORTNAME}-${PORTVERSION}${EXTRACT_SUFX}, you should probably leave DISTNAME alone-- you are better off defining DISTFILES than having to set both DISTNAME and WRKSRC (and possibly EXTRACT_SUFX).
