在heroku上安装taglib

I have a golang app that is using bindings to the C library taglib. When I try to deploy my app, I get the (expected) error that the taglib header file can't be found:

-----> Running: go get -tags heroku ./...
# github.com/wtolson/go-taglib
../github.com/wtolson/go-taglib/taglib.go:6:27: error: taglib/tag_c.h: No such file or     directory

So, I attempted to install taglib using apt-get, but that doesn't work.

~ $ apt-get install libtag1-dev
W: Not using locking for read only lock file /var/lib/dpkg/lock
E: Unable to write to /var/cache/apt/
E: The package lists or status file could not be parsed or opened.

Is anyone aware of how I could install taglib on Heroku?
