This is one way to check for the version of PGF that is installed in an automated way. First create a tex file with the following contents:

\documentclass{article}
\usepackage{tikz}
\batchmode
\makeatletter
\typeout{PGFVersion=\pgfversion
}
\@@end

Say you named it test-pgf-version.tex. Then:

pdflatex test-pgf-version.tex
cat test-pgf-verson.log | grep PGFVersion | sed ‘s/PGFVersion=//’

should display the version number. I happen to need to do this from R so using similar logic:

logFile <- ‘testpgfversion.log‘    
logContents <- readLines( logFile )
match <- logContents[ grep(‘PGFVersion=‘, logContents) ]
version <- gsub([=AZaz]‘,”,match)
print(version)

which accomplishes the same task as the second line above.
