I had to add pycurl to our Solaris 10 image. I hear (in the ether?) that packaging is a bit weird in Python, (pip / easy_install , whatever). Running easy_install pycurl returned

Using curl-config (libcurl 7.23.1)
In file included from src/docstrings.c:4:
src/pycurl.h:145:31: openssl/crypto.h: No such file or directory
error: Setup script exited with error: command 'gcc' failed with exit status 1
So I needed to tell it that OpenSSL lives in /usr/local/ssl on my system, but couldn’t find out how to pass build-ext options to easy_install. It seemed to completely ignore the setup.cfg file I had written for it. So I bailed on easy_install and got the tarball.
Curl-config seems clever – it will just return the right values in case you want to build against it, so I didn’t need to pass it anything about which SSL libraries to use – it just knows and passes it on.
All normal stuff, right. This is the blog worthy part:
python setup.py build_ext --curl-config=/usr/local/bin/curl-config

So how do I change the linker that gcc is using? Apparently you can’t.
gcc -print-prog-name=ld returns:
And the ccs directory contains the Solaris versions of the standard Unix build tools!
So there is a mismatch between the Gnu Compiler and the Solaris linker (maybe?) .
Rerunning with a different $PATH order does nothing here, so don’t bother. This is way nastier. ;o)
mv /usr/ccs/bin/ld /usr/ccs/bin/ld-old
ln -s /usr/sfw/bin/gld /usr/ccs/bin/ld
Note the 'g' in the ld executable, which I assume is for 'Gnu'.
After that it built fine.
