Some notes:

• The revision line should be deleted because it starts at 0.
• Use a sha256 checksum and remove the obsolete sha1 and md5 checksums unless upstream provides them.
• Use the compilers portgroup instead of forcing the use of gcc48 for FORTRAN compiling. See the sparskit for an example of how to use it.
• The license line should be:

license public-domain

• In general, we do not set distfiles directly, it is best practice to set ${distname} and ${extract.suffix} separately.

Thanks for the comments. A revised version of the Portfile is attached.

Added in r118084 with the following changes:

• Added back rmd160 checksum
• Fixed spacing to conform to the modeline.

Note also the following minor warnings that came from the compilers portgroup that I don't know how to fix.

$ port lint --nitpick slatec
