[tahoe-dev] how to build pycryptopp on Mac OS X

[zooko]

Folks:

If you install Crypto++ [1] into the default "/usr" location on Mac  
OS X (by running "make install" in the cryptopp directory), then the  
build of pycryptopp will fail with an error message like "/usr/bin/ 
ld: can't locate file for: -lcryptopp".  If instead you install Crypto 
++ into /usr/local by running "make install PREFIX=/usr/local" then  
everything will work.

I've documented this in the pycryptopp README, and I'll suggest to  
the Crypto++ author that perhaps /usr/local ought to be the default  
value in the GNUmakefile.

Regards,

Zooko
