hi,
i am running slackware 9 and when i try to compile openbox 2.3.1, i get
an error as follows :

make[2]: Entering directory `/misc/downloads/openbox-2.3.1/src'

i do have iconv... and if i do a man iconv_close etc they exist -- i did
some searching and i found that other slackware users had the same
problem but had no problem compiling the non testing version (2.2.3).
i just tried this and openbox 2.2.3 compiles perfectly... but 2.3.1
gives the error above.

3.0 alpha 1 compiles fine as well.  i am yet to run both of them but
they both compile no problem.

thanks,
