zlib is broken

[baldvin@…]

Trying to install zlib failed with checksum error:

kovacs-baldvins-macbook:macports root# port install zlib
--->  Verifying checksum(s) for zlib
Error: Checksum (md5) mismatch for zlib-1.2.3.tar.bz2
Error: Checksum (sha1) mismatch for zlib-1.2.3.tar.bz2
Error: Checksum (rmd160) mismatch for zlib-1.2.3.tar.bz2
Error: Target org.macports.checksum returned: Unable to verify file checksums
Error: Status 1 encountered during processing.

Is it a problem with the package? Unfortunately many things depend on zlib, so I'm pretty much stuck here...

It checksums fine for me, so it's most likely to be a proxy problem (many unfortunately don't report the correct HTTP error code, and so MacPorts saves what it receives when it ought to be discarded). Try cleaning the zlib port's distfiles (sudo port clean --dist zlib), running a selfupdate just to be safe, and then installing with the debug flag (sudo port -d install zlib); if it fails again, the output from the last command should help us diagnose the problem.

Thanks, the issue has been resolved. Below I describe some curiosities about it, for anybody interested:

Interestingly enough, after sudo port clean --dist zlib things got a bit worse:

Neither selfupdate, nor sync made a difference. However, after trying to install with +universal, then cleaning without the --dist option, the installation worked.

Replying to baldvin@cs.elte.hu:

Thanks, the issue has been resolved.

Closing accordingly. The subsequent transient "cannot open file" problem reported in the remainder of comment:2 is curious, but I suspect it's more likely to be a bad sector on the disk or some software problem outside the control of MacPorts.
