LDAP install in Py3 development on Debian Jessie fails (solution included)

Expected Behaviour

Instructions to install LDAP should install LDAP.

Actual Behaviour

sudo python install.py --develop installing automatically switches to Python3 env. Setting up LDAP in erpnext directs to following instructions. By running ./env/bin/pip install python-ldap --global-option=build_ext --global-option="-I$(xcrun --show-sdk-path)/usr/include/sasl" causes an error (also reported here):

~/frappe-bench$ ./env/bin/pip install python-ldap \
>     --global-option=build_ext \
>     --global-option="-I$(xcrun --show-sdk-path)/usr/include/sasl"
-bash: xcrun: command not found

Steps to reproduce:

1. sudo python install.py --develop in python3 env
2. run ./env/bin/pip install python-ldap --global-option=build_ext --global-option="-I$(xcrun --show-sdk-path)/usr/include/sasl"

Suggested temporary solution

Do pip install from repo. In master repo ConfigParser (in py2) vs configparser (in py3) handling is already introduced.

Replace installation instruction with following: ~/frappe-bench$ ./env/bin/pip install git+https://github.com/python-ldap/python-ldap.git --global-option=build_ext --global-option="-I$(xcrun --show-sdk-path)/usr/include/sasl"

ENV:

• ERPNext: v11.x.x-develop (b48557f) (develop)
• Frappe Framework: v11.x.x-develop (a01275d) (develop)
• OS: Debian GNU/Linux 8.10 (jessie)
