In principle, yes.  But actually I did make an error (corrected now).

...which revealed another flaw in the packaging: Build errors do not 
cause FTBFS as it should!

You execute main build routines in a subshell, and shell by default does 
not fail on errors.

I find it most elegant to avoid subshells in make, and I see no reason 
for it here.  When subshell is needed, add a "set -e;" as first command 
inside the subshell to ensure failures are not silenced.

Ah yes, I forgot: Nodejs is only in unstable.  Its main binary "node" 
clashes with another package (a ham radio daemon of some sort). Debian 
Policy then requires one or both of those binaries to be renamed, and 
reaction in the spring was refusal to rename that other one.  Since we 
(I am involved in maintaining Nodejs) feel it is quite bad for the Node 
compiler to be renamed, we have decided to postpone further discussion 
until we can more clearly demonstrate that Nodejs is an upcoming and 
fast growing environment that deserves better care for its naming than a 
ham daemon.

What I do in some Javascript packages is to favor uglifyjs with 
yui-compressor as fallback.  That is relatively simple to setup since 
they use same basic syntax.

See source package "backbone" for an example, if interested.

Remember to build-depend versioned on yui-compressor If you decide to 
add it as fallback!

That was quick!  I would've done exactly like you - but now I noticed a 
little nitpicking flaw in it: yui-compressor simply strips all comments 
but uglifyjs by default preserves topmost comments.  So no there is 
double copyright notices :-P
