libgcrypt, apple-gcc42 & blacklisting ...

[Peter Danecek]

Hi all,

I am trying to upgrade libgcrypt to 1.5.3 on my MacOSX 10.5.8 machine. The Problems are:

1. apple-gcc42 would not compile on that machine, ticket #36648;
2. libgcrypt has some compiler blacklisting logic and therefore seems to select that compiler. 

As a result I cannot build libgcrypt from the box. Now, I am wondering:

1. Is there a way, to list (or to understand) the order in which compilers are applied? 
   Is this documented somewhere?

2. How to append the backlist? 

I tried:
	sudo port -v build libgcrypt "compiler.blacklist-append=apple-gcc-4.2"

but it is ignored.

Is there a way to get the list of the identifiers to use for blacklisting? Where is it documented?

Thanks!
