dmake:  Error: -- `/build/src/build/solver/340/unxlngx6.pro/bin/bsh.jar' not found, and can't be 
made
Retrying /build/src/build/scripting/util/provider/beanshell


with build option:              --enable-ext-scripting-beanshell \

configure logs says:
checking which beanshell to use... external
checking for /usr/share/java/bsh.jar... yes


any idea?
