I used the following setup to create a reproducible clean
environment without interference of possibly set variables.

curl -O http://minimals.contextgarden.net/setup/first-setup.sh
chmod +x first-setup.sh
./first-setup.sh --modules=t-gnuplot
mkdir mymodules
echo '\bold' >mymodules/t-mymodule.tex
echo '\sans' >mymodules/t-gnuplot.tex
cat > test-mymodule.tex <<EOF
\usemodule [mymodule]
\starttext
\input knuth
\stoptext
EOF
cat > test-mygnuplot.tex <<EOF
\usemodule [gnuplot]
\starttext
\input knuth
\stoptext
EOF
source tex/setuptex
export TEXMFHOME=mymodules
context test-mymodule.tex test-mygnuplot.tex

mymodule is loaded and the text is printed in bold, the modified
gnuplot module is not loaded.

test setup:
/home/fusion/tex/texmf-modules/tex/context/third/gnuplot/t-gnuplot.tex
mymodules/t-gnuplot.tex

in my real setup only the distribution file is found. I didn't yet
try to figure out why.

See minimal example above. In my real setup it's

  /home/marco/usr/share/texmf

and it's set in $HOME/.profile using export TEXMFHOME=…

See minimal example above. In my real setup it's

  /home/marco/usr/share/texmf/t-gnuplot.tex

Yes

I didn't know ConTeXt uses kpsewhich.

test setup:
/home/fusion/tex/texmf-modules/tex/context/third/gnuplot/t-gnuplot.tex

real setup:
/home/marco/usr/local/share/context-beta/tex/texmf-modules/tex/context/third/gnuplot/t-gnuplot.tex
