Problem when runs Pod install

[renanstig]

Hello,

Is this library still working? I'm having problems when I try to install it.
This is the erro I'm getting:
[!] /bin/bash -c
set -e
type -P autoconf &>/dev/null || alias autoconf 'xcrun autoconf'
type -P autoheader &>/dev/null || alias autoheader 'xcrun autoheader'

type -P glibtool &>/dev/null || alias glibtool 'xcrun glibtool'
type -P glibtoolize &>/dev/null || alias glibtoolize 'xcrun glibtoolize'

sh autogen.sh
./configure
./tools/svn_repo_revision.sh

/bin/bash: line 2: alias: autoconf: not found

I hope you can help me with that.
Best regards,
Renan.
