This error has me stumped. I configured sqwebmail with the following options:

CPPFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib" ./configure --enable-cgibindir=/usr/local/www/apache22/cgi-bin --enable-imagedir=/usr/local/www/apache22/data/sqwebmail --disable-autorenamesent --enable-hardtimeout=86400 --enable-softtimeout=21600 --enable-autopurge=1 --enable-maxpurge=5 --with-maxargsize=1500000 --with-maxformargsize=5500000 --with-maxmsgsize=6500000 --with-ispell=/usr/local/bin/ispell --prefix=/usr/local

The flags were neccessary, because the config script couldn't find the pcre libs without them. The --prefix looked neccessary, because even though it's supposed to be the default, 'make install' would fail complaining that "/usr/share/sqwebmail" doesn't exist, which makes no sense to me, since it should be putting it in $PREFIX/share/sqwebmail, where $PREFIX is "/usr/local". After setting the prefix option, it now fails with this:

Making install in m4 Making install in po -d /usr/local/share -d:No such file or directory *** Error code 1

Stop in /home/james/packages/sqwebmail-5.1.2/pcp/po. *** Error code 1

Stop in /home/james/packages/sqwebmail-5.1.2/pcp. *** Error code 1

This is really baffling, since "/usr/local/share" does in fact, exist...is this a bug or am I doing something wrong?
