I did update to Mountain Lion after installing MacTeX 2012.

'which pdflatex' gives /usr/texbin/pdflatex. So I added /usr/texbin to my $PATH and now texdoc works as expected. Now 'echo $PATH' gives (for readability, new-lines inserted in output):

/Volumes/MacHD/Applications/Math/Macaulay2-1.4/bin:
/usr/texbin:
/Library/Frameworks/Python.framework/Versions/3.2/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin:
/opt/local/bin:/opt/local/sbin:
/usr/local/mysql/bin:
/Volumes/MacHD/Applications/Math/Singular/3-1-5/ix86Mac-darwin/:
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin

Also, 'ls -alf /usr/' output includes:

rwxr-xr-x     1 root  wheel     63 Jul  8 11:15 texbin -> /Library/TeX/Distributions/.DefaultTeX/Contents/Programs/texbin

BTW, that was surprising, since that target texbin of the /usr/texbin symlink is itself a symlink back to: 

  /Library/TeX/Distributions/.FactoryDefaults/TeXLive-2012/Contents
