Please attach the main.log.

Hi Joshua, I think I have the same problem (very similar error). Here is my main.log: ​https://www.dropbox.com/s/czbuhz22i4sgrsx/main.log?dl=0 thanks, M

What happens if you execute the following from a Terminal window?

/usr/bin/svn --non-interactive --trust-server-cert export http://svn.code.sf.net/p/pymol/code/trunk/pymol@4187

I am seeing no problems with that command used by port here. Perhaps you are running into transient upstream svn down time.

Looks like a network problem, maybe a firewall interfering with svn? If it was sourceforge's server misbehaving then presumably it would affect everyone.

Replying to jmroot: Hi Joshua, Thanks for reply, but still is there any other to install pymol from open source. If you know any other installization process for pymol please let me know. I will try to install by using it. Thank in advance

If the SourceForge svn servers are down or having problems, you'll have to wait until they're back up to be able to fetch and install this port.

But firewalls and proxies sometimes balk at the extended http verbs that Subversion needs to use to check out.

A workaround to that is to fetch via https instead of http. Firewalls and proxies cannot read the contents of the encrypted https connections, and therefore can't interfere with them.

pymol and other ports that fetch from SourceForge svn used to fetch via https, but I changed it to http in [23a487d670a45f85bf17635d5bdabc5caddfc134/macports-ports] because SourceForge began requiring newer https encryption methods than the version of Subversion included with El Capitan and earlier support.

MacPorts 2.4.4 has now been released, which uses MacPorts svn on earlier OS X versions, so fetching from SourceForge svn via https is no longer a problem. So my previous commit should be reverted.
