• I got this error message today when I downloaded and tested SAM-1.3:

  bash: /tmp/1.3/lib/tool/pdb.sam: line 58: syntax error near unexpected token`}'
  bash: /tmp/1.3/lib/tool/pdb.sam: line 58: `}   fi'
  bash: export: pdb: not a function

  No worries!  This is minor, and is actually a good lesson.  It shows what happens when you have a faulty "qualified" function definition.  SAM tries to define and export function pdb, but the system lets you know that it failed in the attempt.

  It seems that I published SAM-1.3 with an error in file pdb.sam.  You may fix the error after installing.  Just move the final "}" down one line, leaving the "fi" in the current line.

  Or you may simply ignore the error message.  Function pdb is not used by SAM.  I intended it as a command for the user.  Unless you need it, nothing is lost by its absence.
