Unicorn fails to install even though it's already installed and running

Unicorn fails to install even though it's already installed and running

[Mac Martine]

I'm deploying a Rails 3.2.8 app to Ubuntu. The server already runs the app with Unicorn and Nginx. 
unicorn -v returns unicorn v4.4.0

Adn rvm gem list shows:
unicorn (4.4.0)

Yet when I manually run 'gem install unicorn '4.4.0' it fails with the following. Any ideas why?

Not sure, yet, (see below)

Then there's also errors which may not be logged correctly: permissions
and out-of-disk-space errors

Maybe gem_make.out will have more info than mkmf.log

That looks fine, actually.  I think any error will be near the end of
mkmf.log.

[Mac Martine]

Thanks,

I can install other gems just fine in the same way, so it doesn't seem like permissions then, right?

And disk space looks ok:
df -h

That's good to know.

Wait, are you now using a different version of Ruby?  Your original
message had 1.9 (via RVM)

Again ^^

However, scrutinizing your original email more:

> >>    "gcc -I/home/evergreen/.rvm/rubies/ruby-1.9.3-p194/include/ruby-1.9.1/x86_64-linux -I/home/eg/.rvm/rubies/ruby-1.9.3-p194/include/ruby-1.9.1/ruby/backward -I/home/eg/.rvm/rubies/ruby-1.9.3-p194/include/ruby-1.9.1 -I. -I/home/eg/.rvm/usr/include     -O3 -ggdb -Wextra -Wno-unused-parameter -Wno-parentheses -Wno-long-long -Wno-missing-field-initializers -Wpointer-arith -Wwrite-strings -Wdeclaration-after-statement -Wimplicit-function-declaration  -fPIC   -c conftest.c"

I see both /home/evergreen/ and /home/eg/ in there; that looks
suspicious.

Did you perhaps copy anything in .rvm/ between home
directories or rename the home directory at some point after
RVM was installed?
