this is the error message I get when installing Rgraphviz. my $LD_LIBRARY_PATH is (I think set correctly) /usr/local/lib/graphviz my graphviz version is 1.12 (although i previously installed 1.13 by mistake) my R version is 1.9.0 I would really appreciate some help! cheers jake :/usr/local/lib/R# R INSTALL Rgraphviz * Installing *source* package 'Rgraphviz' ... ** libs gcc -I/usr/lib/R/include
