Daniel Stenberg and Dan Fandrich,
  
   You both helped me immensely in 2013 when I was with Melissa Data.

I followed the following procedure yesterday.

1. Purge all libcurl files from my Ubuntu Linux 15.10 Lenovo desktop computer.

2. Get libcurl 7.43 source using: sudo apt-get source libcurl4-openssl-dev=7.43

3. Build it for AMD64 , output 64 bit libcurl.so and headers to /home/frank

4. Build it for i386 , output 32 bit libcurl.so and headers to /home/frank

At step 4 , i get the following error stream:

$ make

To recover from these make errors I replaced step 4 with:

sudo apt-get purge libcurl4-openssl-dev*
sudo apt-get install libcurl4-openssl-dev:i386

Our director of software architecture requested that I not use sudo apt-get purge libcurl4-openssl-dev*
because he wants to install parallel 64 bit and 32 bit development packages which both stay intact at the same time.

But when I omit sudo apt-get purge libcurl4-openssl-dev*. all hell breaks loose;

I would like to know how to setup and maintain parallel 64 bit and 32 bit development packages which both stay intact simultaneously.

Thank you.
