Mongodump "command not found" on Cloud9

This question isn’t specific to Meteor, but I imagine someone here might be able to help.

I’m developing in Cloud9’s IDE. Everything has been great so far, but I can’t get mongodump to run. When I try to dump from my Compose server with -h -u -p flags set, I get “bash: mongodump -h command not found”.

which mongodump returns /usr/bin/mongodump, and the command is found when I run mongodump with no flags set.

Anyone know what might be going on?
