[help-GIFT] Compiling gift 0.1.14 on gentoo error

[Kamil Wencel]

Hi List,

I have tried to compile gift 0.1.14 on several machines now and it 
always failed for one or another reason. extensive googling didn't show 
up many results, as it seems that the "gift" is not very common out there.

Since I am curious about QBE technology I really want this to get up and 
running so I can test the gift intensively. If I can get this to work 
with some help here, I would gladly write some docs / howtos.

Now, regarding the building :

./configure --prefix=/usr/local/gift/1.1.14

What could possibly cause this ? Perl Version Missmatch or pthreading
aware / unaware Perl installation ? I tried different gcc versions (3.3 
/ 3.4 ) but had no luck either.

With kind regards,
