unable to fetch certain packages

[vkuznet (Valentin Kuznetsov)]

Hi, I encounter very annoying bug. Recently, I found that I can't upgrade certain ports. I even report a problem with curl package, see bug #39595. Turns out that it is more general problem which I'd like to put into separate ticket. So, certain packages are unable to download from certain URLs. Here is an example of erlang upgrade:

Error: org.macports.fetch for port erlang returned: fetch failed
Please see the log file for port erlang for details:

Error: Unable to upgrade port: 1
To report a bug, follow the instructions in the guide:

as you can see my port was able to fetch erlang-R16B01_0+ssl.darwin_11.x86_64.tbz2, but then fail to fetch otp_src_R16B01.tar.gz from list of URLs. The main.log shows the following

from main.log
debug:fetch Fetching distfile failed:: The requested URL returned error: 403

for those URLs. Then port command exit with error status. I observed the pattern that this only happens from aforementioned URLs, while other URLs are working fine, for instance here is successful gcc upgrade

--->  Attempting to fetch gcc47-4.7.3_1.darwin_11.x86_64.tbz2 from http://packages.macports.org/gcc47
--->  Attempting to fetch gcc47-4.7.3_1.darwin_11.x86_64.tbz2 from http://mse.uk.packages.macports.org/sites/packages.macports.org/gcc47

--->  Verifying checksum(s) for gcc47

So, I was unable to upgrade the following list: otp, curl, mongodb, clang, nginx, py27-sqlalchemy, but at the same time I was able to successfully upgrade gcc, mercurial, etc.

I really don't know what's going on, but I don't have any proxy. For the reference, I have OSX 10.7.5 and recent port version 2.1.3

Any suggestions are really welcome, Thanks, Valentin.
