Hi Marco,

Do you have an example of a LaTeX file that uses packages only in 
texlive-collection-latex but fails to compile if 
texlive-collection-latexrecommended is not installed?  Without this, 
it's very hard for me to check if the occurrences of "pdftexcmds.sty" 
that you found really indicate dependencies.  My technical knowledge of 
LaTeX is not good enough to determine this just from looking at the .sty 
files.  See below for further comments on a few of the occurrences.

The previous line contains "IfFileExists", but I can't parse that line 
well enough to know if it prevents a problem.

This is wrapped in an \if...\else that I can't parse.

The previous line contains "IfFileExists".

Doesn't "IfFileExists" prevent a problem in this case?

"pdftexcmds.sty" occurs only in a comment.
