OK, Please verify that config.c looks like this:
#define ND 4
void FindBlas(FILE *fpout, FILE *fplog, char *redir, char *F77, char *F77FLAGS,
char *BLASlib)
{
char **files;
char *dirs[ND] = {"", "/usr/lib", "/usr/local", ""};
char ln[256],pwd[256],*pp;
int i, j, n;
FILE *p;
ATL_mprintf(2, fplog, fpout, "Looking for BLAS (this may take a while):\n");
if (*BLASlib)
{
sprintf(ln,
"cd CONFIG ; make IBlasLink F77=\"%s\" F77FLAGS=\"%s\" BLASlib=\"%s\"
%s\n",
F77, F77FLAGS, BLASlib, redir);
if (system(ln) == 0)
{
ATL_mprintf(2, fplog, fpout, "BLASlib set to %s.\n", BLASlib);
return;
}
ATL_mprintf(2, fplog, fpout, " Link failed, %s rejected\n", BLASlib);
}
if (!(p=popen("pwd","r"))) {
if (fpout) fprintf(fpout, "Can't open pwd pipe\n");
if (fplog) fprintf(fplog, "Can't open pwd pipe\n");
return;
}
if (!fgets(pwd,sizeof(pwd),p) || !(pp=strchr(pwd,10))) {
if (fpout) fprintf(fpout, "Can't read pwd line\n");
if (fplog) fprintf(fplog, "Can't read pwd line\n");
return;
}
*pp=0;
if (pclose(p)) {
if (fpout) fprintf(fpout, "Can't close pwd pipe\n");
if (fplog) fprintf(fplog, "Can't close pwd pipe\n");
return;
}
/* if (sizeof(pwd)-(pp-pwd)<6) { */
/* if (fpout) fprintf(fpout, "pwd array too small\n"); */
/* if (fplog) fprintf(fplog, "pwd array too small\n"); */
/* return; */
/* } */
/* snprintf(pp,sizeof(pwd)-(pp-pwd),"/BLAS"); */
dirs[0]=pwd;
dirs[ND-1] = getenv("HOME");
for (j=0; j < ND; j++)
{
n = FindFiles(dirs[j], "lib.*blas.*\\.a", &files);
if (n)
{
for (i=0; i < n; i++)
{
sprintf(ln,
"cd CONFIG ; make IBlasLink F77=\"%s\" F77FLAGS=\"%s\" BLASlib=\"%s\"
%s\n",
F77, F77FLAGS, files[i], redir);
if (system(ln) == 0)
{
strcpy(BLASlib, files[i]);
ATL_mprintf(2, fplog, fpout, "BLASlib set to %s.\n", BLASlib);
return;
}
ATL_mprintf(2, fplog, fpout,
" Link failed, %s rejected\n", files[i]);
}
}
}
ATL_mprintf(2, fplog, fpout,
"Unable to find usable BLAS, BLASlib left blank.\n");
BLASlib[0] = '\0';
}
#undef ND
Then you can either strace -f the make config (or xconfig), or run
under a debugger and see why the stat fails on your machine.

I neglected to tell you you needed to set the following environment
variables before this step, as in debian/rules:
ARCH_DIR=Linux_$*_shared CACHE_SIZE=$(CACHE) DEFAULTS=$(DEFAULTS)
The last two can be set to blank, the first is the build name.

Please, as soon as we are convinced that this is a local configuration
issue, could we please close this? Many other machines report no
problem. This is not to say that it is not a subtle atlas bug, but
odds are ....
Take care,
