  I puzzled out that...

checksums           molmol-2k.2.0-src.tar.gz md5 e1f4416d8041a67fa08cadb03ed91c7c \
                    molmol-2k.2.0-src.tar.gz sha1 09482a1dea601563ca64e773dc0ec47019e22c63 \
                    molmol-2k.2.0-src.tar.gz rmd160 b1de89953631dd9b11928751d7853cb511bf45f0 \
                    molmol-2k.2.0-doc.tar.gz md5 517545b60b0179ab691a679ed29903a7 \
                    molmol-2k.2.0-doc.tar.gz sha1 b47551283fa19f57f4d5edcbd52f725055d80b7f \
                    molmol-2k.2.0-doc.tar.gz rmd160 08b3e21ab6eb7c9044e59373334181ff91ca8a53

works. I've run to another issue though. The molmol-2k.2.0-src.tar.gz and molmol-2k.2.0-doc.tar.gz
tarballs extract out their files without creating an enclosing source directory so that...

COPYING			auxil			makedef.aix.mesa	makedef.lnx.mesa	makedef.sun		src
HISTORY			data			makedef.aix.opengl	makedef.sgi4		makedep			tiff-v3.4
INSTALL			help			makedef.dec		makedef.sgi5		makedep.devel		tips
Makefile		include			makedef.dec.mesa	makedef.sgi6		man			tools
README			lib			makedef.gen		makedef.sol		molmol
README.UNIX		macros			makedef.hp		makedef.sol.mesa	setup
README.WIN		makedef.aix		makedef.lnx		makedef.sol.opengl	sg

are directly splattered into /Users/howarth/ports/science/molmol/work. In fink, this didn't matter but MacPorts shares the work
subdirectory with the source and destroot subdirectories. What is best practices here for this case. Do we have
a Portfile option to modify how the distfiles are extracted?
